the theory to extract angular error is described and the realization of millimeter radar「s digital phase comparator and extracting method of angular error」s sign are discussed.
论述了如何利用和差三通道的一维距离像来获取三维图像的实现方法。
a circuit called a phase comparator causes the vco to seek and lock onto the desired frequency, based on the output of a crystal-controlled reference oscillator.
