摘要：
The paper presents a detection performance of the LFM radar signal using the Radon transform. Such a transform 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).
