Abstract

This paper presents an analytical derivation of the effects of Doppler shift on the optimal signal processing of frequency-stepped CW radar data. It is shown that successive CW measurements produce a shift in the global minimum of the objective function which can be tracked as a function of time. The amount of time shift in the global minimum can be used to extract the target velocity. Once the target's velocity has been established, accurate estimates of target position are obtained. Simulation results are presented that illustrate the process of velocity and range information extraction from the Doppler-shifted frequency-stepped CW data.
