Monte Carlo method and the eigen-driven analysis method are combined to simulate the effects of errors on side-lobe level distribution of the Ultra-low side-lobe arrays.
采用本征激励法,在考虑互耦影响下,数值模拟了幅度误差、相位误差、位置误差和不平行度偏差等对超低副瓣阵列天线方向图性能的影响。
Analysis shows that, only when the size of the hole is larger than 0.2 wavelengths will the variation of the antenna gain and the side-lobe level become obvious.
分析发现,只有当孔径大于一定的尺寸(约0 . 2 0个波长)时,天线增益和副瓣电平才会发生明显变化。
Using this method the side-lobe level is suppressed more through double weighting in time domain.
采用双加权的失配处理分析方法,在时域进一步降低压缩脉沖的旁瓣电平。
