摘要

本文介绍了利用Radon变换和Hough变换对LFM雷达信号的检测性能。这样的变换从时频图像中提取直线方程。本文研究的主要问题是截获接收机对LFM信号的自主搜索过程。假定有关信号持续时间和延时的先验信息是未知的。在这种情况下，信号的WVD可能会分裂，性能特性会下降。对不同的移动窗宽、搜索速度和信噪比进行了计算机仿真。

LFM radar signal detection in the joint time-frequency domain

The paper presents a detection performance of the LFM radar signal using the Radon and Hough transform. Such a transforms extracts the line equation from the time-frequency image. The main problem which is considered in the paper is the autonomous search process of the LFM signal by the intercept receiver. It is supposed that a priori information concerning the signal duration and time delay is unknown. In this case the WVD of the signal can be splitted and performance characteristics degrade. The computer simulations are carried out for different values of the moving window width, search velocity and signal-to-noise ratio (SNR).
