目标截面积 meaning in Chinese

target cross section

To simulate return accurately , we set several models as follows : target radar cross section ( rcs ) model , target antenna modulating model , target wave modulating model , noise model , clutter amplitude distributed model and power spectrum distributed model . each of these models has been analyzed and simulated
分别建立了目标截面积起伏模型、目标天线方向图调制模型、目标波形调制模型、噪声模型、杂波幅度分布和功率谱分布模型,对每种模型的建立进行了分析和仿真。
