| Abstract: Acceleration performance is an important technical indicator of dynamic characteristics of the satellite navigation signal simulator.Only theoretical analysis and researches have currently been applied to measure acceleration performance of the simulator,with lack of practical and feasible test methods in daily testing work.With the research of the Doppler effect,this paper analyzes the measurement principles,builds a dynamic performance test platform and carries out experiments to verify the correctness,practicality and effectiveness of the test method. |
