Embodiment Construction
[0011] refer to figure 1 . Within the uncertain range of the Doppler frequency deviation, the Doppler frequency of the receiver can be divided into multiple groups of frequency slots with equal intervals or non-equal intervals; the division of the frequency slots is based on the Doppler dynamic range of the signal, and the signal frequency The accuracy requirements for tracking, while considering the complexity of the circuit and digital chip resources, can generally be divided into 3 to 10 frequency slots. The setting of the frequency slot can adapt to different dynamic tracking. If the signal Doppler dynamic is low and high frequency tracking accuracy is required, the frequency slot can be divided more finely; if the signal Doppler dynamic is high, the frequency slot should be set wider; The frequency slots near the center slot can be divided finely, and the frequency slots far away from the center slot can be divided wider, which can not only meet the tracking accuracy but...
