Signal Sorting & Identification Of Anti-Radiation-Radar-Seeker

Being the all-important and decisive component in the Anti-Radiation-Mi ssile(ARM),the capability of the Anti-Radiation-Radar-Seeker(ARRS) directly influence the performance of the ARM. The aim of this paper is focused on the study and improvement of the method of signal sorting and identification of ARRS. So this is of great importance for the ARM.A detailed investigation is given on the method of the general radar signal and the jam signal sorting and identification of ARRS in the complicated spatial signal environment with the aid of .the method of signal characteristic.The emphasis is put on the spatial angle identification of the unsolved jamming signal in the time and frequency field. Two methods of the spatial angle separation is given: the clustering analysis and the power centroid track, and the advantages and the shortcomings of these methods are discussed with the theoretical analysis and the emulational result. The result shows that these methods are both feasible and practical, and they can effectively separate several closed targets in the space, and improve on the tracking performance of ARM.
