Adaptive Waveform Design Based on WLS-TIR for Multiple Targets Recognition in Cognitive Radar

FAN Mei-mei1,LIAO Dong-ping1,DING Xiao-feng2,LI Xiang1(1.School of Electronic Science and Engineering,National University of Defense Technology,Changsha,Hunan 410073,China;2.Unit 96627 of PLA,Beijing 100085,China)  
A method of adaptive waveform design for multiple targets recognition is proposed.It includes three main parts:first,a new information theoretic criterion which is the mutual information between the received signal and the weighted linear sum of the target impulse responses(WLS-TIR) is proposed;second,a method of calculating the weights is developed;third,a strategy of adaptively adjusting the waveforms for multiple targets recognition is present.The simulation results show that the proposed method increases the performance of a radar system apparently for multiple targets recognition,besides,it is realistic and feasible.
