摘要
Abstract
According to the sea level fluctuations and variations under different sea conditions and wind conditions,this paper studies the sea clutter by use of the compound Gaussian process description method,and puts forward a method of extracting sea clutter texture component.By using the proposed method,the decorrelation time of the measured sea clutter texture components can be analyzed,and the best coherence length of the texture components can be adaptively searched.Thus,the separation of the texture component from the speckle component of the sea clutter can be completed.Based on the X band radar sea clutter data,this paper also analyzes the extraction efficacy of sea clutter texture component in different resolutions and different polarization conditions.The simulation results show that the method has good application value in the analysis of the sea clutter statistical characteristics and the improvement of radar signal detection performance.关键词
