AI Technical Summary
Technical Problem
Modern radars struggle to automatically identify noise or deception interference when faced with complex electromagnetic environments, leading to a decline in their detection capabilities.
Method used
By setting a fixed threshold to detect radar echoes, statistically analyzing the distribution of threshold points in the angular domain, and combining this with constant false alarm rate processing, the angle measurement results are segmented to determine whether the radar is being interfered with.
Benefits of technology
It enables automatic identification of interference in complex electromagnetic environments, improving the radar's detection capability and anti-interference performance.

Abstract
一种基于角度测量的干扰检测方法，将雷达回波信号预处理，得到基带和差信号，在雷达噪声基底上增加一个门限，得到检测结果，设置一个大于1的系数，乘以单个强目标的回波信号对应的过门限点的数量，统计过门限点的数量，如果大于乘积，则对检测结果逐点测角，得到角度测量结果及其在方位和俯仰的分布范围，分割为数个单元，如果方位和俯仰都存在某个角度出现的次数大于乘积，则判定雷达受到干扰。
