The satellite navigation signal simulation system, which can simulate the signal Doppler received by terminal in the high-speed projectile spin, can provide effective testing and evaluating method for the development of low-cost trajectory correction projectile technique based on the satellite navigation system. After analysis, it is pointed out that when the projectile spin Doppler of received signal is simulated using classical piecewise polynomial method, the simulation parameters' update period will be dramatically reduced, and the computation load will also be significantly increased. To solve this problem, the concepts of rigid body micro-motion and micro-Doppler are introduced and simulation technique of projectile spin Doppler based on the micro-motion of a rigid body is proposed. By taking the micro-Doppler characteristics parameters, which is produced in the process of high-speed projectile spin flight, as simulation parameters, the problem of the reduction of Doppler simulation parameter's update period can be solved effectively. The simulation results show that while simulating the projectile spin Doppler generated by spin frequency of 100 Hz, the proposed method can satisfy the requirements of spin Doppler simulation error at the update period of simulation parameters of 100 ms, far superior to the classical piecewise polynomial method which needs the requirement of less than 1 ms.
