摘　　要：基于对某航天器用救援示位标的测试需要,针对示位标低码速率调相、调幅双重调制射频信号的特点,介绍了一个接收脉冲射频调相信号的接收机.接收机实现了下变频、脉冲射频载波恢复和基带信号解调.研制成功的锁相接收机已经应用于某航天器示位标的测试,得到了满意的结果.A phase-locked receiver applied to receive pulsed PSK radio frequency is introduced to meet the requirement of a certain spacecraft beacons test, which is based on the characteristics of the low code rate PSK and ASK dual modulation radio frequency signal. The receiver achieves multiple functions such as frequency down conversion, pulsed carrier recovery, phase-modulation demodulation. The phase-locked receiver has been used to test the beacons of a spacecraft. The application results prove this attempt to be successful.
