Since its inception during World War II, radar has continued to be a topic of significant im‐ portance in both military and civilian contexts. Although the reflectivity of electromagnetic waves was first investigated by the German physicist Heinrich Hertz around 1886, its value, in a military context, was not realised until experimentalists in the United Kingdom, the United States and Europe found that the presence of aircraft could be detected via remote sensing, providing a significant early warning advantage. This resulted in much research and development of radar technology and then applications of it to aircraft traffic control as

Although radar began as an experimental science, it was found that its performance could be modelled by studying the environment in which it operated and also enhanced by designing its underlying algorithms on the basis of the theoretical developments. With improvements in electronics and technology, it was found that it was necessary to develop better algorithms to

Thus, there continues to be a lot of interest in the development of radar signal processing algorithms for modern radar applications. This book thus provides a sample of contribu‐ tions to modern radar signal processing. This includes a series of chapters examining syn‐ thetic aperture radar (SAR), multiple-input multiple-output (MIMO) radar, micro-Doppler processing, as well as analysis of waveforms, radar detection, and clutter suppression is‐ sues. It is hoped that the chapters in this book would provide readers with future directions
