| 摘 要： | 在电子侦察领域中，传统的雷达脉冲信号检测是基于包络检波的非匹配检测。为了提高在低信噪比条件下对雷达脉冲信号的检测概率和参数估计精度，文中提出了一种新的雷达脉冲信号的非匹配检测算法——极值序列分析法。该算法可在低信噪比条件下完成雷达脉冲信号的检测，然后对雷达脉冲信号的脉冲幅度、脉宽、到达时问、信噪比和载频等参数进行估计。仿真结果表明：极值序列分析法对雷达脉冲信号的检测概率高、参数测量精度高和处理速度快。 |

| Abstract: | In the electronic reconnaissance area, the conventional detection method of the radar pulse signal is based on nonmatched envelope detection. In order to improve the detection probability and the parameter precision of the radar pulse signal in the condition of a low SNR, a novel nonmatched detection algorithm, called extremum sequence analysis method, is put forward in this paper. It can be used to detect the radar pulse signal and estimate its parameters, such as PA, PW, TOA, SNR and RF. The simulation results show that this algorithm has a high detection probability, a high parameter measuring precision and a fast calculation speed. |
