Doppler Frequency Shift Simulation Based on High Dynamic Motion Model

In order to realize carrier acquisition and tracking of high dynamic link better,Doppler frequency shift between high dynamic aircraft and near space receive plat is described and simulated in terms of the motion models of high dynamic aircrafts in near space,and based on the result,the influence on carrier synchronization caused by Doppler frequency shift is discussed.Analysis and simulation results show that Doppler frequency shift achieved in terms of high dynamic motion models can accurately describe Doppler shift trends under high dynamic movement.
