后回波 meaning in English
post echo
Examples
- In the same time , a better algorithm to suppress side lobe after match filtering is presented , which is based on the analysis of component and residual of imfs . it is found that the algorithm reduces the shortage of emd algorithm and the high resolution image of sar is obtained under noise condition
本文的主要工作如下: 1 、在sar成像应用中,通过分析匹配滤波前后回波的emd分解结果,得出emd分解在流程中的位置;通过对imf分量与余量的分析,给出了优于常用方法的抑制匹配滤波后回波旁瓣方法,并克服emd方法自身的某些缺点,从而在含噪声条件下使sar成像结果更加清晰。
