This chapter surveys some of the more advanced pulse compression (PC) waveform modulations and techniques applied in modern radar systems, including stretch processing, stepped chirp waveforms, nonlinear frequency modulated (NLFM) waveforms, stepped frequency (SF) waveforms, quadriphase codes, and mismatched filters (MMFs) applied to phase codes. Fundamentals of phase and frequency modulated PC waveforms are covered.
