Delay and Doppler resolutions analysis of radar phase-coded pulse and frequency-coded pulse

For classic radars, pulse compression is an important way to improve range and velocity resolution. And phase-coded and frequency-coded signals are two important means to implement pulse compression. In this paper, we analyze the lower bound of delay and Doppler resolutions of radar phase-coded pulse and frequency-coded pulse. The lower bound of the delay-Doppler resolution of phase-coded waveform is obtained. Meanwhile, the delay resolution of radar frequency-coded waveform is discussed and two useful propositions are gotten. We also get an approximate result for Doppler resolution of frequency-coded waveform. At last, the paper is concluded and future works are pointed out.
