Deceptive Jamming Suppression Via Segmented Modified Radon-Fourier Transform for Moving Target Detection

Considering the moving target detection in the complex electronic countermeasures environment, the interference characteristic analysis and suppression method in the presence of the across-range unit effect are desperate for further exploration. This article is an expeditionary study under a typical moving target detection scenario where a self-defense jammer generates multiple fast-forwarding range-Doppler joint deception false targets. The disparity features between the true and false targets are revealed under the coherent integration methods, i.e., modified radon-Fourier transform (MRFT) and segmented MRFT (SMRFT). Utilizing the otherness of range support zones of false targets in different segments under SMRFT, an SMRFT-based interference suppression (SMRFT-IS) architecture is proposed to eliminate false targets with the energy of the true target retained as much as possible. Simulation results verify the validity of the derived features of true and false targets and demonstrate the effectiveness of the SMRFT-IS algorithm in false target elimination.
