Half-Fourier transform and application to radar signals

In this paper we discuss the Half Fourier Transform (HFT) and explore its application to radar-return signals with specular components. It is shown that this transform enables separation of the desired part from the specular impulsive components. The effectiveness of this technique and the computer program developed, is demonstrated by simulation examples. Our program uses an optimization package which performs minimization of a nonlinear sum-of-squares functional with a model trust region strategy.
