Abstract

The approach to simulate satellite signal Doppler frequency shift in high dynamic condition based on FPGA is investigated. Third-order DDS model is built and its output phase expression is derived. The corresponding relationships between designed parameters of DDS and signal Doppler are analyzed and a guide line to choose proper parameters is provided. Simulation results indicate that using this method to simulate signal Doppler is of high precision in high dynamic motion with jerk.
