Abstract: For dim target detection under low signal-to-noise ratio, the traditional detection algorithm uses constant false alarm rate（CFAR）to locate the target, but it is difficult to set an appropriate threshold, which cannot well deal with the detection of this kind of targets. Aiming at the above problems, this paper proposes VU-NET detection method. Firstly, the radar echo data is processed to obtain the range-Doppler（RD）matrix of the target echo. Then the RD matrix is input to the proposed network f... More
