摘要:

针对相控阵雷达工作状态（跟踪或搜索）识别提出了一种基于脉冲幅度统计直方图的快速识别方法。首先，分析了相控阵雷达波束调度的时序特征，然后引入了一种改进的直方图方法对雷达脉冲幅度进行统计分析，通过峰值检测的方法进行跟踪状态初判，最后综合数据率和平均单次驻留时间进行精确识别。仿真结果表明：该方法可以在1s内准确判定雷达工作状态，识别雷达目标跟踪个数，并且具有较强的鲁棒性，可以为雷达告警、电子对抗情报侦察等多种应用场景提供参考。

Abstract:

A fast identification method based on pulse amplitude statistical histogram is proposed for phased array radar operating state (tracking or searching) recognition. Firstly，the time sequence characteristics of the phased array radar beam scheduling are analyzed. Then an improved histogram method is introduced to analyze the radar pulse amplitude，and the tracking state is rough judged by the peak detection. Finally，the data rate and the average dwell time are used for accurate recognition. The simulation results show that this method can accurately identify the operating state and target tracking number of the radar within one second sample time and has strong robustness，which can provide reference for many applications，such as radar alarm，ELINT，etc.

Key words: phased array radar radar operating state recognition histogram pulse amplitude radar warning receiver (RWR) electronic support measure (ESM)
