针对毫米波大气衰减对海上毫米波RCS测量试验的影响,利用Matlab对测量数据进行回归分析,并建立毫米波大气衰减模型,最后通过方差分析和回归效果分析等,对毫米波大气衰减模型进行评估检验。该模型的建立有效地提高了外场毫米波RCS测量精度。
Aiming at the effect of millimeter-wave atmospheric attenuation on the millimeter-wave RCS measurement experiment at sea, the regression analysis of the measurement data by Matlab and the establishment of a millimeter-wave atmospheric attenuation model are carried out. Finally, the millimeter-wave atmospheric attenuation model is evaluated by analysis of variance and regression analysis test. The establishment of this model effectively improves the measurement accuracy of the field millimeter RCS.
