Information extraction for multi-mode seeker automatic target acquisition

The information extraction technique for multimode seekerspsila automatic target acquisition is presented. A new multi-mode active radar seeker for long-range air-to-air missile is put forth, which has pulsed Doppler mode and linear frequency modulation mode to switch. Firstly the scheme of the multi-mode seeker is described, and then the information extraction algorithm based on super-resolution frequency analysis for handover and algorithm based on monopulse 3-D profiling for endgame intercept are presented respectively. The simulation result shows that the idea is valid.
