In the vast blue ocean, ships of different navies operate far from each other and are generally not in visual range. However, a ship can be uniquely identified based on a number of emissions that are characteristic to each and are called signatures. These include acoustic signature from machinery and flow, heat or infrared signature from exhaust, radar cross section from hull surfaces, magnetic signature from hull material, electric signature from corrosion protection systems etc. These signatures are used by surveillance and tracking sensors for attacking ships in general and warships, in particular. Survivability at sea requires management of all platform signatures to produce a net effect of reduced vulnerability. Anti-ship missiles pose the greatest threat to ships at sea. Prior to the Second World War, studies were carried out in parallel on the use of radar and infrared seekers in missiles for detection, identification and homing. For the materials available in the 1940s, radar seekers gave better results and hence, have become the standard fit. Over the years, advances in material sciences have improved the capabilities of infrared seekers and today, missiles have several guidance/seeker options that include radar, electro- optical camera and infrared imaging. Infrared homing is preferred for terminal guidance because of its inherent immunity to jamming techniques. A stealthy naval platform remains undetected and therefore can be deployed closer to the target to fulfill its mission with lesser risk of damage and associated causalities. Signatures used for ship detection include both underwater and above water. Signatures used by underwater weapons like torpedoes and mines are acoustics, magnetics, wake homing and extremely low frequency emissions (ELFE). Anti-ship missiles use above water signatures that include laser cross section (LCS), radar cross section (RCS), air borne noise and infrared (IR).

Modern wireless communication systems require high data rates to provide acceptable quality of service. However, this poses challenges in the allocation of spectrum, which is a scarce re- source. To overcome this, the Multiple Input Multiple Output (MIMO) con¿guration has been developed, which has excellent spectral e¿ciency and data rates, as proven by mathematical modelling. The major hurdle in wireless communication systems is achieving good isolation between antenna elements while also maintaining a miniaturized structure. Therefore, reducing mutual coupling and signal correlation is essential for better performance. In recent years, there has been a remarkable evolution in satellite systems, leading to enhanced reliability in mobile communication. Initially, satellite performance was constrained, necessitating the use of large ground station antennas and öering only limited services. However, with advancements, satellites have become more robust, capable of delivering a broader spectrum of services with improved quality. Multiple Input Multiple Output (MIMO) has emerged as an important technology for enhancing the e¿ciency and data rates of wireless networks and terrestrial communication standards. Consequently, there is growing interest in employing MIMO techniques in satellite communication systems. However, implementing MIMO in satellite communication poses unique challenges in comparison to the terrestrial domain. As the demand for satellite capacity continues to grow, MIMO has emerged as a promising solution to increase spectral e¿ciency without the need for additional power. The utilization of the spatial domain is the primary source of enhanced channel capacity. Extensive literature exists that provides a comprehensive review of MIMO techniques speci¿cally designed for satellite communication.

Wireless communication is the backbone of the digitized society, where everything is connected and intelligent. Access points and devices are nowadays equipped with multiple antennas to achieve higher data rates, better reliability, and support more users than in the past. This book gives a gentle introduction to multiple antenna communications with a focus on system modeling, channel capacity theory, algorithms, and practical implications. The basics of wireless localization, radar sensing, and controllable reflection through reconfigurable surfaces are also covered. The goal is to provide the reader with a solid understanding of this transformative technology that changes how wireless networks are designed and operated, today and in the future.The first three chapters cover the fundamentals of wireless channels, and the main benefits of using multiple antennas are identified: beamforming, diversity, and spatial multiplexing. The theory and signal processing algorithms for multiple-input multiple-output (MIMO) communications with antenna arrays at the transmitter and receiver are progressively developed. The next two chapters utilize these results to study point-to-point MIMO channels under line-of-sight (LOS) and non-LOS conditions, covering the shape of signal beams, impact of array geometry, polarization, and ways to achieve reliable communication over fading channels. The book then shifts focus to multi-user MIMO channels, where interference between devices is managed by spatial processing. The next chapter extends the theory to multicarrier channels and explains practical digital, analog, and hybrid hardware implementations. The last two chapters cover the role of multiple antennas in localization and sensing, and how reconfigurable surfaces can improve both communication and sensing systems.The text was developed as the textbook for a university course and builds on the reader's previous knowledge of signals and systems, linear algebra, probability theory, and digital communications. Each chapter contains numerous examples, exercises, and simulation results that can be reproduced using accompanying code.

Over the past few years, there has been an incredible rise in demand for wireless communication technology that supports high data speeds, exceptional spectrum efficiency and excellent broad band fading reduction. Due to changes in how information is generated, shared, and used by today's society, data traffic has rapidly expanded in the wireless realm. There won't be enough spectrum left for wireless technology to manage these high data rates, hence new spectral bands will be needed. This has now come up with the usage of the Terahertz (THz) frequency band (0.1-10 THz). This band is often known as the THz gap since the technology for generating and detecting terahertz radiation is still in its infacy. It is the frequency range between millimeter-wave and infrared that has received the least attention to research fraternity. In order to satisfy the need for 5G and B5G (Beyond 5G) networks, the spectrum between 0.1 and 10 THz is regarded as a scientific innovation. The development of miniaturized antennas in these bands of frequency leads to the miniaturization of the antenna into the range of millimeters or micrometers. For instance, there is an increase in wireless data by 200% for every three years. This in turn, is making the wireless data rate to reach the point where it is almost comparable with the wired communication systems. The antenna required for faster connectivity anywhere at any time has grown in tandem with this trend. Applications for terahertz technology include static point-to-point networking in server rooms or high-performance computer, as well as short-range ultra- broadband accelerated wireless connectivity. The large cable connections in server rooms or supercomputers might be replaced by such an antenna. For the transmission of signals, researchers are looking for SubTHz and THz frequency bands (0.1 THz-10 THz), since very high data rates within a confined duration are becoming the major goal in the emerging communication field. The SubTHz frequency band (0.1 THz) experiences less reduction in signal strength due to atmospheric factors like rain and fog compared to the upper band of THz band, which leads to a spectrum with increased capacity for data transmission. Terahertz frequency communication links are crucial in situations that demand high data rates over short distances. With the help of these frequencies, rapid data transmission can be achieved within a span of 10 meters. There are presently 23 billion devices linked to the internet, and it is predicted that there will be 75 billion devices online by the year 2025.

Underwater wireless communication system designers have been confronted with an ever-increasing need for high-capacity and high-data-rate wireless applications for real-time image and video transmission. Acoustic wireless communication (AWC) has been preferred inside the water over a long-range communication (a few kms). However, due to having a drawback of low data rate (upto kbps) in AWC, the visible light communication (VLC) is growing attention as an attractive alternative to AWC, as VLC supports high data rate. Di¿erent sorts of light transmissions, such as horizontal, vertical, and slant, are possible. When visible light travels through an underwater channel, it encounters a variety of negative factors due to the interaction of the light wave with underwater constituents. Path loss and turbulence are two of the most critical factors that cause severe fading. Path loss quanti¿es the amount of power a signal loses as it travels through a communication channel. Underwater turbulence occurs due to the change in refractive index of the water, thereby causing random ¿uctuations in the received signal strength. This phenomenon is referred as turbulence-induced fading. The main cause of change in refractive index is variation of temperature, eddy particles and pressure inside water. Since surface of the sea is directly imposed with sun rays and due to which the temperature of the surface water is higher as compared to the temperature of deeper dark water. Visible Light Communication refers to optical wireless communication systems that operate in the visible band (390 ¿ 750 nm). LEDs or lasers are used in VLC systems because they can be pulsed at very high speeds without äecting the lighting output or the human eye. The use of LEDs is a sustainable and energy- e¿cient strategy for both illumination and communication. The properties of sea water are transparent to blue and green light (450 nm to 530 nm) and exhibit low attenuation. Underwater VLC is able to provide data rate up to Gbps in a real-time environment. In the Underwater VLC system, spatial diversity has proven to be an e¿ective and widely used technique to alleviate the e¿ects of fading and improve the performance of communication systems. In spatial diversity, several parallel communication links are formed between transmitter and receiver by employing multiple transmit and/or receive branches (MIMO systems).
