| 摘 要： | 介绍一种反辐射导弹发射时机警设备的基本原理和实施方案。根据雷达收到的载机和反辐射导弹回波信号特征，综合成ｅｘｐ（Ｊ２π（ｆｏ＋ｆｄ）ｔ）信号和ｅｘｐ（ｊ２π（ｆｏ＋ｆｄ＋ａｔ／２）ｔ）信号的数学模型。分雷达跟踪波门内外两种情况进行５１２点快傅里叶变换（ＦＦＴ）谱分析，从频域上把载机和导弹区分开来，达到反辐射导弹发射时机靠警的目的。最后给出了仿真结果，结果是令人满意的。

| Abstract: | The basic principle and implementing plan of an ARM alarm equipment are presented. Based on the echo characteristics of a plane and an ARM,their mathematical models, exp (j2 (f0 + fd ) t ) and exp (j2 (f0 + at/2 ) t ), are synthesized. According to the results of 512 points compensation FFT in and out the radar tracking wave gate,an ARM is distingished from a plane in the frequency domain. The simulation results are alse given, and they agree with theoretical ones very well. |
