The processing of pulse Doppler radar signals is commonly depicted as a sequence of stages known as the processing chain. Signal processing is applied to enhance the signal-to-noise ratio (SNR) to enhance detection performance, to discriminate between true targets and interference, clutter, or jamming, and to extract the desired information about targets that, at the very least, includes target range and velocity. While the exact order and processing operations differ from radar to radar, they are all likely to include the stages depicted in Figure 7-1.
