Radar Signal !!better!! ★

A simple pulsed radar signal can be described as:

The radar signal is a carefully designed information carrier whose parameters—time, bandwidth, modulation—define system performance. From simple pulsed signals to adaptive cognitive waveforms, the evolution of radar signals mirrors advances in digital signal processing and RF hardware. Key challenges remain in designing waveforms that simultaneously achieve high resolution, low sidelobes, Doppler tolerance, and spectral coexistence with communication systems. radar signal

After matched filtering, the output envelope is a function with first nulls at (\pm 1/B). LFM is Doppler-tolerant (slight frequency shifts cause small range shifts but minimal SNR loss). Wireless Pi 1m Radar signal characteristics - Wikipedia

Sub-Nyquist sampling of the radar return exploits signal sparsity (few targets in range-Doppler space). Random or pseudo-random waveforms enable reduced data rates.
