摘要
叙述了在密度加权相控阵上进行的随机馈相和波束置零实验。得到了随机馈相抑制副瓣电平的结果。指出了副瓣电平抑制量与扫描角位置和移相器位数有关。证实了用相位加权置零实数算法在最大副瓣处置零可以很好地抑制该副瓣的电平,在波束其它方向置零效果也很好。
Experiments of the phase control null and random phase quantization in density weighted phased arrays are described. Conclusions about control of parasitic sidelobe levels with random phase quantization algorithm are verified experimentally. The experiment results confirm that parasitic sidelobe levels are related with the direction of scanning angle and the bits of phase shifters. The control of sidelobe level at some points or over some intervals with real phase only nulling algorithm (REPONA) are verified experimentally too.
