Abstract :
This paper proposes the instantaneous polarization radar measurement method of the PSM (polarimetric scattering matrix) using the up and down chirps for the motive target with a uniform acceleration; it defines a new ambiguity function matrix considering Doppler frequency shift and acceleration in order to get the PSM of target. This paper also gives the signal processing and the expression of the PSM for a target moving at a uniform acceleration. The simulation results of missile-defence radar prove the feasibility of the presented method, which enhances the precision in measurement of the PSM compared to the traditional method.
