摘要
比较了模拟相控阵和数字相控阵在波束合成过程中信号分量与镜频分量的不同变化,分析它们对波束合成结果的影响,并提出在数字相控阵中判断镜频的思路。
The different variations of the signal and mirror components of the analog and digital phased array radars (PARs) in the DBF are compared to analyze the effects on the results of the DBF, and the idea of determining the mirror frequency in the digital PARs is presented.
