Moving Target Indication (MTI) and pulse Doppler processing are thoroughly treated. Topics include staggered PRF to resolve blind speeds, clutter filtering via digital filters, and the use of the Discrete Fourier Transform (DFT) for velocity estimation. New content addresses staggered PRF selection strategies.
Radar signal processing bridges analog front-end hardware and high-level target detection, tracking, and imaging. Richards’ third edition updates classic material to reflect computational advances and new waveform designs. This review outlines the fundamental blocks: from the received echo to the detection decision. fundamentals of radar signal processing third edition pdf
Abstract Mark A. Richards’ Fundamentals of Radar Signal Processing, Third Edition remains a cornerstone text for understanding the mathematical and algorithmic foundations of modern radar systems. This paper synthesizes the core topics presented in the book, including the radar range equation, matched filtering, Doppler processing, CFAR detection, and emerging techniques like cognitive radar. Emphasis is placed on concepts new or expanded in the third edition, such as advanced pulse compression waveforms and knowledge-aided adaptive processing. Moving Target Indication (MTI) and pulse Doppler processing
A core principle: the matched filter maximizes output SNR for a known signal in white noise. Richards covers ambiguity functions for LFM, phase-coded, and nonlinear FM waveforms. The third edition adds discussion of windowing for sidelobe control and stretch processing for wideband LFM. Abstract Mark A
Constant False Alarm Rate (CFAR) detection adapts to changing noise and clutter. Richards explains cell-averaging (CA-CFAR), ordered-statistic (OS-CFAR), and more recent methods like adaptive CFAR for non-homogeneous environments. The third edition expands on CFAR losses and two-parameter CFAR for clutter edges.
The book begins with a complex baseband representation of the radar signal, enabling efficient processing. The range equation incorporates noise figure, losses, and pulse integration gain. The third edition clarifies the relationship between SNR, probability of detection (P_d), and false alarm rate (P_{fa}).
