Abstract: To effectively recognize the phased-array radar, a method based on the analysis of the intercepted pulses amplitude characteristics is proposed. On the basis of the difference in the scan of phased-array radar and conventional mechanical scanning radar, a model of the pulses amplitude intercepted by surveillance equipment is set up, which can obtain the characteristics of pulses amplitude intercepted from different system radar by simulation. It obtains the resemble coefficients between the sine sequences and the pulses sequences intercepted from different systems radar. According to this, it recognizes the phased-array radar. The proposed method is proved.

Key words: phased-array radar, scanning mode, pulse amplitude, resemble coefficient

摘要： 为有效识别相控阵雷达，提出了一种基于截获脉冲幅度特性分析的识别方法。该方法根据相控阵雷达与常规机械扫描雷达的扫描方式存在很大差异的特点，建立侦察设备截获脉冲的幅度模型，并通过仿真得到不同体制雷达被截获的脉冲幅度特性。求得不同体制雷达被截获的脉冲序列幅度特性与正弦序列幅度特性的相似系数，以此为依据来识别相控阵雷达。通过比较实验证明了该方法的有效性。
