Radon Spectrum and Its Application for Small Moving Target Detection

Abstract

Analogous to the radar Doppler spectrum for coherent processing, the concept of a Radon spectrum that is a kind of normalised Radon transform is proposed and used for radar non-coherent detection. One advantage of using the Radon transform for non-coherent processing is that integration in all directions is considered, and hence range migration of moving targets is not a concern. The detection processing is based upon a 2D Radon spectrum that is transformed from the original range-time 2D radar image. The threshold and the probability of detection for a given false-alarm rate are determined in the same way as the traditional non-coherent integration. Both simulated and real radar datasets are tested and the effectiveness of the proposed technique is demonstrated.
