摘　　要：提出了基于去冲激响应的UWB雷达目标识别方法,在理论上对该识别方法进行了详细地推导,并给出了该方法中所用到的窄脉冲的选取准则;最后,通过计算机模拟,给出了两种飞机模型不同姿态下的近似冲激响应数学模型,在此基础上对这两种飞机模型进行了识别仿真。从仿真结果来看,此识别方法效果良好。A method of UWB radar target recognition based on eliminating impulse response is put forward. The process of target poles extraction can be skipped when this method is used in target recognition. This target recognition method is deduced theoretically in detail, the rule of selecting narrow pulse is presented. Finally, the mathematical models of approximate impulsive response about two aircraft in different pose are obtained via computer simulating. Based on these models, two aircraft models are recognized. Simulation results show that this UWB radar target recognition method is effective.
