Dynamic echo simulation of precession target based on electromagnetic scattering model
Dynamic echo is the basis to analyze and discriminate the features of precession targets, but it is difficult to acquire the outfield data with small cost. In this paper, precession model of a general target is built, and the attitude formulas of elevation and azimuth are derived respectively. On the basis of the static electromagnetic scattering data, a scheme is proposed to simulate the dynamic echo of an arbitrary precession target by using the quasi-static method. Its validity is verified by the experiment results, and the RCS sequences and micro-Doppler signatures of two representative targets are analyzed based on the simulated echo.
