| 摘 要： | 在分析外辐射源雷达中参考通道与目标回波通道信号特点的基础上,提出了在外辐射源雷达分析模型中,不使用参考通道,仅仅利用目标回波通道的数据信息,完成对目标的检测,进行时延和多普勒频率参数的提取。在对目标进行角度估计时, 为了实现多目标的参数匹配,给出了已知波形匹配算法和比幅测向的角度参数估计算法,通过仿真实验说明了所提方法的有效性。

| Abstract: | he passive radar signal characteristic of the reference channel and the target echo channel are analyzed and a target detection method by eliminating the reference channel but taking use of the target echo channel data information is proposed to extract time delay and Doppler frequency parameters of the target. When estimating direction of arrival (DOA), the known waveform matching algorithm and the amplitude comparison and angle measurement approach algorithm are presented to realize multi targets parameter matching. The methods are proved to be efficient by computer simulations. |
