大型相控阵天线相位量化瓣的相关抑制法

Interrelation Restraint Method of Quantized Phase Sidelobe for Large Phased Array

相控阵扫描量化瓣的抑制方法,基于移相器量化相位结尾误差的进位概率以及进位概率的相关传递,有效地抑制了由有限移相器位数引起的相控阵扫描量化瓣,极大地降低了抑制大型相控阵扫描量化瓣的计算优化时间。作为一个实例,设计了一个大型相控阵,得到了一次运算抑制大于5dB的抑制效果。

Based on the probability and the probability interrelation transfer on the up - bit for the shifter, restrain method of quantized sidelobe for the phased array is proposed. It is effective method for reduction the quantized sidelobe and saves the optimal computation time. For example, restraint quantized sidelobe is computed for a large phased array amd 5dB quantized sidelobe reduced is obtained only by one computation time.
