An Improved Detection Algorithm of Moving Targets Based on Envelope Alignment in Sea Environments
Pages 40 - 45
Abstract
Detection algorithm has been widely applied in water surface targets detection. However, the traditional algorithm cannot effectively detect those slow moving targets. This paper proposes a modified detection algorithm to improve accumulation gain while eliminating positional deviation of imaging output. First, the echoes of non-cooperative target are compensated by azimuth filtering. The range pulse compression and radar speed compensation are implemented subsequently. To effectively correct the range walk caused by target motion, range alignment based on profile correlation is performed. Ultimately, the aligned signals are accumulated through azimuth Fast Fourier Transform (FFT). Effectiveness of the proposed method is verified by experimental results based on simulated data.
