摘　　要：针对船用雷达图像消噪问题 ,提出了应用小波包分析算法对雷达图像进行消噪处理。小波包分析算法对上一层的低频部分和高频部分同时进行细分 ,具有更为精确的局部分析能力。本文对小波包分析进行了改进 ,解决了频率混叠问题 ,其消噪效果更佳 ,具有更为广泛的应用价值。Aiming at the problem of noise elimination of radar p icture, a way to employ wavelet packet analysis to eliminate noise of radar pict ure is proposed. By means of the wavelet packet analysis, the low frequency part and high frequency part of the superstratum can be concurrently further broken down, and therefore, more exact analysis of localities can be conducted. Based o n the above, wavelet packet analysis is improved, the problem of frequency band overlap is solved, and very good effect of noise elimination is achieved. The re sult may be received widely in application.
