Digital signal processing (DSP) of RADAR signals, compared with analog, causes:

Digital signal processing in radar improves weak-signal detection and target enhancement by enabling sophisticated manipulation of the received signal once it's in digital form. By digitizing the waveform, we can apply matched filtering to maximize the response to the expected pulse, perform pulse compression to boost range resolution and signal-to-noise ratio, and coherently integrate successive returns from a potential target. These techniques help suppress clutter and noise, adapt to changing interference, and set detection thresholds more effectively. The result is noticeably better detection of faint targets than with older analog processing. Other effects like display quality or interference with sonar or other radio equipment aren’t direct outcomes of DSP in radar.
