Here's a unique new resource that offers you a solid understanding of the fundamental theory, operation principles and applications of shortrange frequency modulated continuous wave (FMCW) radar. You learn how to choose the structural scheme of shortrange FM radar, and determine the optimal algorithm of useful signal processing necessary for ensuring the technical characteristic of radar. Moreover, this practical reference shows you how to ensure the minimum level of radar signal parasitic amplitude, calculate modulation signal distortion, and compensate for nonlinear distortion. For the first time in any book, you find detailed coverage of the theory and calculations of autodyne radar, helping you avoid typical mistakes with your work in this area. Other critical discussions include the parameters of UHF unit output signals and the principles of regime optimization. Supported over 750 equations, the book saves you valuable time in solving problems, so you can focus on your analysis. The original application of lowcost, lightweight FMCW radar technology was in proximity fuzes for artillery projectiles, where production lots of thousands or more were typical, with small size, low cost, reliability and freedom from jamming vulnerability were essential features. Little has been published in this area because of the military nature of the application. More recently, as the technology has become familiar to engineers in civil areas, applications to industrial measurements and vehicle navigation have become apparent. Here, also, the advantages of small size and low cost make FMCW radar technology suitable for largescale use in the industrial and consumer market. With the information available for the first time in this book, many new applications will be found for shortrange FMCW radar.
