This chapter deals with Doppler techniques and their different applications for surveillance radar, multifunction radar and synthetic aperture radar. The chapter presents: an analysis of a simple pulse Doppler radar [fixed station, low pulse repetition frequency (PRF), no range ambiguity] (radar characteristics, power and spectra of clutter and target, basic block diagram of the radar, practical considerations and implementation); a similar radar with range ambiguity (medium PRF); shipborne surveillance pulse Doppler radar; airborne surveillance radar (general description; low, medium and high PRF modes); combat aircraft radar (radar characteristics; look-up and look-down operation in low, medium and high PRF modes; examples and comparison of the modes); solving range ambiguities in medium PRF (MRF) and high PRF (HRF) modes; and synthetic aperture radars.
