基于时频分析的带腔体雷达目标弱信号检测

Weak Signal Detection of Cavity Embedded Radar Tanget Based on Time-frequency Analysis

该文论述了在强噪声背景下利用时频分析检测带腔体雷达目标弱信号的方法。利用时频分析方法对目标的一维像进行分析 ,提高了雷达在强噪声背景下对微弱目标信号的检测能力 ,使利用恒虚警检测无法检测到的目标经过时频分析处理后 ,可以被正确地检测出来。

A new method based on Time Frequency Analysis (TFA) for detecting weak signal under strong noise background from radar target with the cavity embedded is described in this paper.The detecting ability is improved by applying TFA to the target range profile.The target that can not be detected by applying Constant False Alert Rate (CFAR) method can be detected correctly by this approach.
