This cutting-edge resource introduces the basic concepts of passive bistatic radar, such as bistatic geometry, bistatic radar equation and analysis of different illuminating signals. These techniques, although known for almost a century, have not been developed intensively for decades, mainly due to technical limitations, but today, the passive radar concept can be realized in practice, and is of great interest for military and civilian users. This book provides insight into understanding the potential and limitations of passive radar systems, as well as the differences between signal processing in active and passive radar. Each of the signal processing stages typically applied in passive radar is described, including digital beamforming, clutter removal, target detection, localization and tracking. These concepts are illustrated with both simulated and measured data along with examples of passive radar systems. Correlation processing, which is crucial for passive radar operation, is presented, as well as practical approaches for calculating the cross-ambiguity function. The problems of range and velocity-cell migration are also introduced. The book analyzes and compares different antenna array geometries to show readers the appropriate solution for a particular scenario of passive radar. Cartesian tracking is also presented, based on the extended Kalman filter. Parallel and sequential updating approaches are introduced and compared. These concepts are illustrated with both simulated and measured data along with examples of passive radar systems, making this book useful for both novice and advanced practitioners.

This book is devoted to the emerging technology of noise waveform radar and its signal processing aspects. It is a new kind of radar, which use noise-like waveform to illuminate the target. The book includes an introduction to basic radar theory, starting from classical pulse radar, signal compression, and wave radar. The book then discusses the properties, difficulties and potential of noise radar systems, primarily for low-power and short-range civil applications. The contribution of modern signal processing techniques to making noise radar practical are emphasized, and application examples are given.

The impact of bistatic radar technology on remote sensing is increasing as bistatic systems cross the theoretical threshold into practical embodiment. The wide spectrum of radar applications, including space exploration, defence, transport, aerospace, and meteorology, provides persistent impetus for this progress. This book is dedicated to the more advanced studies in bistatic radar which are currently the subject of intensive research activity and development. With contributions from the leading experts in the field of bistatic radar research, this book collates the latest developments in the field focusing particularly on bistatic synthetic aperture radar (BSAR) and passive bistatic radar systems (PBRS). Within these two areas the text: addresses the main BSAR topologies: spaceborne BSAR, airborne BSAR and space-surface BSAR; analyses the resurgent interest in, and practical applications of, PBRS; introduces passive BSAR technology; covers research of systems used in aircraft detection and tracking, and passive radar remote sensing of the ionosphere and the upper atmosphere. Bistatic Radar: Emerging Technology is an invaluable resource for practising engineers and researchers involved in the design and implementation of advanced bistatic radar systems in aerospace, communications, defence, transport and meteorology. Following on from Bistatic Radar: Principles and Practice it is also a comprehensive reference on the latest research for postgraduate students taking specialist courses in radar technology.

Statistical signal processing for signal parameter estimation is an ever-evolving field, with continuous research for efficient methods for the ever-changing needs of various systems that require signal processing tasks to be accomplished. Three types of parameter estimation techniques exist: parametric, nonparametric, spectral, and Bayesian. Over the past fifty years, digital signal processing has seen a virtual surge in ideas, techniques, and applications for military and commercial products/systems. The radar is one such system that is extensively employed for detecting and locating target objects. Radars can perform well for long or short distances and under conditions unreceptive to infrared and optical sensors. These qualities render a complex system that can operate in darkness, rain, snow, fog, and haze. Therefore, radar finds use in various surveillance, defense, space, ship and aircraft navigation, and remote sensing applications. These critical applications accentuate the significance of radars and prompt scientists and researchers to continuously improve the efficiency of signal processing algorithms in terms of accuracy and computational complexity. In this dissertation, we have considered two types of radar signals for our study; the multiple sinusoids, which models a radar interference signal, and a passive bistatic radar (PBR) signal. The issue of multiple sinusoid estimation is a fundamental research problem that has been the topic of research for a long time. Passive bistatic radar has also recently gained traction due to its widespread military and civilian use for surveillance and stealth purposes. Under the parametric estimation approach, the maximum likelihood estimator (MLE) is the most widely used practical method that provides optimally accurate estimates and achieves the Crámer-Rao lower bound (CRLB) for the radar signals mentioned above. However, its computational complexity is enormous if we use the grid search (GS) technique for maximization of the likelihood function of the data. Thus, other iterative methods were devised instead of GS, like Gauss-Newton technique. Still, the MLE is a computationally costly approach, and iterative algorithms require an excellent initial guess and do not guarantee convergence to the maximum. In this thesis, we have proposed a novel hybrid technique that combined two statistical concepts of data-supported optimization (DSO) and contracting-grid search (CGS) to reduce the time-complexity of grid-search based MLE (GS-MLE). The proposed estimator, named data-supported contracting GS-MLE (DSC-GS-MLE), has been found to be computationally efficient compared to GS-MLE for two and three sinusoid cases. It also yielded estimates close to that of GS-MLE and achieved the Crámer-Rao lower bound (CRLB) like GS-MLE, a performance benchmark for estimators, for two sinusoids. We found that the proposed DSC-GS-MLE approach was still computationally burdensome. To circumvent this problem and make the estimators more practical, prior information about the parameters could be incorporated into the estimators. This is accomplished using Bayes' theorem, where we use prior knowledge in the form of a PDF. Two Bayesian techniques are minimum mean squared error (MMSE) and maximuma- posteriori (MAP), which require multidimensional integration or optimization. However, using GS or EM techniques for these purposes still caused computational complexity issues. Fortunately, Markov chain Monte Carlo (MCMC) methods provide an alternative cheaper solution in this regard. Metropolis-Hastings (MH) is the most general and frequently used MCMC.

Radar has been an important topic since its introduction, in a military context, during World War II. Due to advances in technology, it has been necessary to refine the algorithms employed within the signal processing architecture. Hence, this book provides a series of chapters examining some topics in modern radar signal processing. These include synthetic aperture radar, multiple-input multiple-output radar, as well as a series of chapters examining other key issues relevant to the central theme of the book.
