Spinning Targets Imaging Based on OMP Algorithm with Radial Basis Function
A new radar imaging method is proposed for spinning targets in space. The rapid spin motion of the target induces multi-period sinusoidal modulation of the radar echoes in both range and doppler domain, which causes Range-Doppler (R-D) algorithm invalid in conventional radar imaging. The presented method analyzes the echo model of the target spinning around an arbitrary axis. An exponential radial basis function (RBF) is then constructed from the scatters range profile based on a distanceweighted criterion, and the image is rebuilt by recovering the projection of the target base on orthogonal matching pursuit (OMP) algorithm with the radial basis matrix. The simulation results show that the proposed method can obtain the radar image more effectively for the target with a uniform speed spin motion.
