复杂环境下的智能恒虚警算法分析

Analysis of Intelligent Constant False Alarm Algorithm in Complex Environments

阐述由于复杂的地理、电磁环境影响,目标信号很有可能湮没在噪声或杂波之中,导致漏警。同时雷达可能会将强杂波区域检测为目标。提出一种复杂环境下的智能恒虚警算法。该算法根据分类网络的输出,采取不同的恒虚警算法进行处理。实验结果表明,原先采用常规恒虚警算法无法检测的目标信号,可以通过所提出的智能恒虚警算法检测出来。

This paper expounds that due to the influence of complex geographical and electromagnetic environments,the target signal is likely to be submerged in noise or clutter,leading to missed alarms.At the same time,radar may detect strong clutter areas as targets.Propose an intelligent constant false alarm algorithm in complex environments.This algorithm adopts different constant false alarm algorithms for processing based on the output of the classification network.The experimental results show that target signals that were previously undetectable by conventional constant false alarm algorithms can be detected by the proposed intelligent constant false alarm algorithm.
