Measurement estimation in forward scatter radar with a planar array

A technique is presented for estimating the primary measurements of forward scatter radar with a planar array. The space-time processing based on three-dimensional discrete Fourier transform is employed and the computation is reduced without loss of accuracy. By analyzing the Cramer-Rao lower bound, the performance of the given approach is shown. Meanwhile, the effect of the target´s complex scatter coefficient to the Doppler measurement is noticed. Numerical simulation presents an estimation of primary measurements with good accuracy.
