According to the principle of view the Doppler frequency detection, the detector makes up of the transmitter, the transfer circuit, receiver and signal processing circuit.
In the satellite navigation and positioning system, Doppler shift is one of the key problems that may degrade the performance of the satellite receiver.
在卫星导航定位系统中，多普勒频率偏移是影响接收机性能的关键因素之一。
