Abstract :
It is shown that if the pulse-repetition frequency of a coherent pulse-Doppler radar is at least twice the Doppler bandwidth, one may, using appropriate downconversion, sample the radar signal at half the Nyquist rate with no loss in range resolution and no folding of Doppler frequencies. This results in a 3-dB loss of signal-to-noise ratio
