Abstract: A series of analyses and research were done to test the impulse thrust of the rocket engine accurately.The principle of the dynamic compensation was used to make compensation for attenuation viration curce of impulse thrust.First the dynamic calibration of the force transducer was completed,then the dynamic mathematic model of measuring system was build.According to the mathematic model,compensated filter was designed and the compensation was verified by the computer simulation.Finaly tested thrust data processing,data smooth,FFT frequency analysis and compensated filter were accomplished.A very practical software package of dynamic measuring system calibration and data processing was designed with C language.
