主　　题：Six detection screen array Multi-projectile Recognition and matching Temporal and spatial information constraint Wavelet transform 

摘      要：The dynamic parameters of multiple projectiles that are fired using multi-barrel weapons in highfrequency continuous firing modes are important indicators to measure the performance of these *** characteristics of multiple projectiles are high randomness and large numbers launched in a short period of time,making it very difficult to obtain the real dispersion parameters of the projectiles due to the occlusion or coincidence of multiple *** six intersecting-screen testing system,in this paper,we propose an association recognition and matching algorithm of multiple projectiles using a temporal and spatial information constraint *** extract the output signal from each detection screen and then use the wavelet transform to process the output *** present a method to identify and extract the time values on which the projectiles pass through the detection screens using the wavelet transform modulus maximum *** then use the correlation of the output signals of three parallel detection screens to establish a correlation coefficient recognition constraint function for the multiple *** on the premise of linear projectile motion,we establish a temporal and spatial constraint matching model using the projectile’s position coordinates in each detection screen and the projectile’s time constraints within the multiple intersecting-screen *** then determine the time values of the multiple projectiles in each detection screen using an iterative search cycle registration,and finally obtain the flight parameters for the multiple projectiles in the presence of *** proposed method and algorithm were verified experimentally and can solve the problem of uncertainty in projectiles flight parameter under different multiple projectile firing states.
