Introduction

This introduction presents an overview of the key concepts discussed in the subsequent chapters of this book. The book provides brief introduction to monostatic radar, bistatic radar, multistatic radar, multiple-input–multiple-output radar, and netted radar system. It provides basic theoretical concepts such as the matched filter theory and the ambiguity function are reviewed. The waveform properties of the frequency-modulated radar pulses are investigated, which include the linear frequency modulated waveform and the stepped frequency waveform. The book focuses on target detection, measurements, and imaging using radar networks. Then the book also provides the basic statistical signal estimation concepts such as the minimum variance unbiased estimator, the Cramer-Rao lower bound, the best linear unbiased estimator, the maximum likelihood estimator, the least-squares estimation, and the Bayesian estimation approach.
