When electromagnetic (EM) coupling exists, false peaks occur periodically in high-resolution range profile (HRRP). These false peaks restrict the improvement of the success rate of the target recognition based on HRRPs. Therefore, identifying these false peaks and removing them is crucial, but has not been thoroughly investigated in the open literature. This letter first studies the EM coupling mechanism in a multiobject system according to the iterative physical optics theory. Then, templates to match the false peaks are constructed based on the established EM coupling theory. Next, cross correlation is performed to recognize and remove the false peaks. To verify the presented method, a metallic multitriangle model is used. The simulation results show that the proposed method can remove the false peaks and find the accurate locations of the metallic triangles. Finally, the practicability of the method is proved through experimental measurement results.
