This article analyses in the high dynamic condition the acquisition arithmetic for PN code by DMF （digital matched tilter） and builds the simulation system with MATLAB/SIMULINK. The analysis about simulation results in different parameters validates the system and also displays the characteristics in the real-time and validation aspects. Simultaneously the origin of these characteristics is also discussed. In the end the prospect of the system is pointed out.
