摘　　要：针对船用雷达图像消噪问题,提出了应用改进小波包分析算法对雷达图像进行消噪处理,解决了频带混叠问题,提出了最优小波包基的确定方法,分析了消噪原理,并通过对雷达图像的消噪处理和比较,其消噪效果优于小波,具有更为广泛的应用价值。Aiming at the problem of noise elimination of radar pictures, the improved wavelet packet analysis is presented to the noise elimination of radar pictures, and it solves the problem of block overlap of frequency bands, in addition, the method of selecting the best wavelet packet basis is also put forward and the principle of noise elimination is analyzed. By simulation, the result is superior to wavelet transform and the value of its application is wider.
