针对运用载频、脉宽和重频等常规参数识别相控阵体制的雷达对先验知识的依赖程度较高的问题，通过建立合理的截获雷达脉冲幅度模型，对雷达对抗侦察设备截获的信号脉冲幅度的变化规律进行了分析；通过构建幅度差值序列，计算脉冲的幅度差均值，实现了相控阵体制雷达的自动识别。仿真结果验证了该方法的有效性和可行性，为雷达体制的识别尤其是一维、二维相控阵雷达的识别提供了一种有效的思路。

Aimed at the problems that the dependence degree of priori knowledge is higher while employing the carrier, pulse-width and repetition frequency as well as other conventional parameters to identify the phased-array radar systems, the changing rules of signal pulse amplitude intercepted by radar countermeasure reconnaissance equipment is analyzed by setting up a proper model for interceptive radar pulse amplitude. And by constructing the amplitude difference series and computing the mean of pulse amplitude difference, the automatic recognition of the phased-array radar systems is realized in this paper. Experimental simulation results prove this proposed scheme to be of effectiveness and availability, which brings about an effective thinking way for recognition of radar systems, especially one dimensional and/or two dimensional phased-array radar.
