To improve the testing accuracy and detection probability of the burst location parameter of projectile, this paper put forwa rds three infrared area array CCD intersection measurement method, sets up the infrared radiation characteristics model of projecti le by using the surface element mesh analysis method and the bidirectional reflection distribution function, analyzes and derives the output signal function of projectile’s radiation in unit area array CCD detection module; studies the relationship between the spectrum detection rate and the radiant energy, gives the calculation method and calculation function of detection rate of three infrared area array CCD. Through the calculation and analysis, the calculation results show the target radiant energy is m aximum when the flight path of projectile is orthogonal with the optical axis of infrared area array CCD; the larger the radiation of projectile, the greater the spectrum detection rate of testing system ; this paper give s the experiment result on the detec tion capture rate of three infrared area array CCD intersection measurement systems the experimental results are basically consistent with theoretical calculations, which verify the calculation model is scientific..
