通过多通道合成的功率值解算实现了对相位差的求解.对算法的机理分析和外场实验表明

这种校准技术正确有效.

Abstract

From the principle of signal synthesis

a new outfield calibration method is presented based on phase interferometric

and phase difference formula is derived with the combination of overdetermined equations solution.Special state shift is realized with phase shifter

and phase difference is obtained by multiple channel power synthesis.The mechanism analysis and the outfield experiments show that this method is efficient and correct.
