Study about Test Ammunition Terminal Effectiveness with the Velocity Radar

摘要

The paper analyzes the fragment movement rule when the ammunition exploded. The mathematics model of the fragment radar echo signal is established on the basis of the principle of the movement targets modulating Doppler signal. The simulation data processing was achieved in using FFT method for the fragment echo signal. Quantitative analysis was realized about the influence for the signal processing precision by the fragment amount, the velocity difference value between the fragments and SNR.
