中/远程防空导弹通常采用复合制导体制，并采用高抛弹道技术来增大射程。这样，在中末制导交班阶段或末制导阶段，主动雷达导引头需要在地/ 海杂波背景下截获和跟踪目标。介绍了一种计算主动导引头地/海杂波功率谱的方法，根据杂波功率谱的估算结果，可以确定导引头的杂波下可见度(SCV)指标或设立导引头跟踪的频率禁区。

Complex guidance is often used in medium and long range surface to air missile, with parabolic trajectory used to increase range. Thus, in the stages of midcourse and terminal guidance transition or terminal guidanc e active radar seeker often needs to intercept and track target in severe land/s ea clutter background. A novel method of land/sea clutter power spectrum calcula tion for active radar seeker is introduced in this paper. According to estimat ion results of clutter power spectrum, it can be used in designing seeker's subc lutter visibility performance, or setting frequency tracking prohibited regions for the radar seeker.
