摘要 为了进一步改善低信噪比条件下E脉冲目标识别方法的性能,该文理论分析了渐近无偏E脉冲目标识别方法,指出其存在E脉冲二次滤波使其能量识别数失效和回波中不同极点互藕产生新极点分量从而降低目标识别概率等缺陷,在此基础上提出了一种先互相关再E脉冲滤波的修正渐近无偏E脉冲雷达目标识别新方法,并对其渐近无偏性进行了理论证明。基于三种不同尺寸有限长细导线目标理论计算后时响应的仿真实验表明,该文提出方法的性能大大优于传统E脉冲和渐近无偏E脉冲雷达目标识别方法。 In order to improve the performance of the E-pulse target discrimination scheme in low signal-noise-ratio （ SNR）, in this paper the asymptotically unbiased E-pulse Based method for target discrimination are theoretically analyzed. Its shortcomings that double filter operation in the method invalidated its energy discrimination number and the target discrimination probability is lowed by new pole components due to coupling between different poles in target echo are shown clearly. Then a modified asymptotically unbiased E-pulse based method for target discrimination is proposed,in which the target echo is firstly cross-correlated and secondly filtered by E- pulse filter. Moreover the asymptotically unbiased characteristic of the proposed method is deduced. The simulations based theoretical late-time response of three finite thin wires with different size show that the proposed method is more superior to the traditional E-pulse scheme and asymptotically unbiased E-pulse based method for target discrimination.
