摘要 针对多个雷达目标的识别问题,研究认知雷达的波形自适应方法,对目标冲激响应线性加权求和获得多个目标的加权表示,基于互信息准则,通过最大化接收到的信号与目标冲激响应线性加权和(WLS-TIR)的互信息获得了针对多目标识别的最优波形,给出了权值的计算方法和多目标识别的自适应机制.仿真实验表明,本文提出的方法相对于传统的线性调频信号(LFM)对多目标的识别性能有明显的提高,并具有较强的实用性和可行性. 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.
