Our analysis indicates that multiresolution analysis has the disadvantage of miss some scatterers, especially for relative regular scattering, however, using the time frequency graph of continuous wavelet transform can obtain the better result.

分析结果表明，对规则性较强的散射体用多分辨分析容易产生漏检，而利用连续小波变换时频图则可以得到较好的效果。
