Measuring Target Velocity with Multistatic Radar System

The velocity measurement in three dimensions is of important significance for target detection and analysis. In this paper, a new and effective ardar waveform for uncoupling time delay and Doppler shift and its ambiguity function of the waveform is analyzed first. An algorithm for measuring a target velocity vector with multistatic short range radar system is analyzed. Formulae for the calculation of velocity vector are derived with independent of transmitter position coordinates, witch is very suitable for the case when the transmitter is not fixed. System performances are simulated with the present algorithm and the results are presented for various conditions.
