Abstract

Aiming at the influence of high acceleration modulation of the linear FMCW (LFMCW) radar echo signal in the short range and high resolution applications on missiles, satellites, and planes, we derive the expression of acceleration resolution for the LFMCW signal. It is concluded that the acceleration resolution is inversely proportional to the square of the effective time width. We also analyze the influence on the Doppler resolution and time delay caused by the unknown acceleration. It is concluded that the increase of time width does not necessarily enhance the Doppler resolution, because of the existence of acceleration, delay resolution decreases with the increase of unknown acceleration. Computer simulations justified these conclusions.
