本文包括顺序波束相频扫天线阵随机指向误差分析和相频扫天线阵阵面随机误差模拟结果.这里所推导的公式比简化公式有更好的结果。公式适合于顺序波束扫描方式,但对差波束进行类似的推导也可得到单脉冲体制的公式.这里的公式适合于相扫和频扫,按比幅方式处理,对比相方式要重新推导最后一式.阵面模拟用一个波导窄边缝隙相频扫阵作为实例进行计算机模拟,证实了公式的实用性,并达到预测天线性能和规定公差的合理数值.
This paper includes the random directional error analysis of sequential beam and phase frequency sweep antenna arrays and the simulation results of random error of phase frequency sweep antenna array surface.The formulas derived here have better results than the simplified ones. The formula is suitable for the sequential beam scanning method, but a similar formula for the differential beam can also be derived single pulse system formula here formula is suitable for phase sweep and frequency sweep, the ratio of processing, the contrast phase to re-derive the last formula Front-surface simulation A waveguide narrow-side-slot phase-frequency sweep was used as an example to simulate the practicality of the formula and to achieve a reasonable value for predicting antenna performance and specified tolerance.
