雷达侦察系统采集相位的测频技术

介绍了采集相位测频的速率以及等间隔相位采集实现测频的基本方法。分析了利用相位延时方法的相位延时滤波器和双回路解调的测频技术，讨论了随机相位波动产生频率的变化，以及衡量频率波动的测量频率范围内的最大均方根值误差。

FREQUENCY MEASURING TECHNOLOGY OF COLLECTING PHASE OF RADAR RECONNAISSANCE SYSTEM

The basic method to collect the rate of phase frequency measurement and to achieve frequency measurement with equal spacig phase collection is introduced. The frequency variation in random phase undulation and Max. Root mean square error in the range of measured frequencies to measure frequency undulation are discussed through the analysis of the phase delay filter which uses a phase delay method and the frequency measuring technique with double loop demodulation.
