Analysis of the Impact on Doppler Frequency Shift of the Signal Caused by Receiver’s High Dynamic Environment

Abstract:

The Doppler frequency shift of the signal received from receiver carrier in high dynamic environment which means high speed and high acceleration represents different changing rules. The changing rules can make the positioning accuracy become worse and even make the receiver unable to track the signal. On the basis of modeling and simulation of three high dynamic carriers including the aircraft, satellite and ballistic missile, the changing rules of Doppler frequency shift were analyzed using the calculation equation of the Doppler frequency shift. The results show that for the high dyanmic carriers, the larger the velocity of the carrier is, the larger corresponding Doppler frequency shift is and the larger the acceleration of the carrier is, the larger corresponding changing rate of Doppler frequency shift is.
