Aiming at the actual requirements of fragment speed measurement,a method for the processing of light screen target measurement data as well as a speed error propagation model are developed.The matching technology of both the target signal waveform and the fragment orbit is studied.Based on the unbiased estimation,the scopes of random error for parameters such as time and distance are determined.And the total error of fragment speed measurement are given with considering the time and distance matching errors.

Explosion equivalent quantitative evaluation of global blowup warhead changes with many factors such as explosive payload and charging type etc. To get some relatively accurate experimental result, concluded and analysed the empirical formula of the shock-wave propagation laws, and built the computational analysis model, which achived the explosion equivalent quantitative evaluation of global blowup warhead.The quatitative evaluation with the model enhances the confidence of the damage experimental result.
