Abstract

In order to resolve the difficulty of massive laser target signal channels during testing barrage weapons dispersion, a modularized system connected with parallel data acquisition scheme based on field-programmable gate array (FPGA) and central processing unit was presented. Trajectory parameter, data acquisition speed and storing velocity of the measured projectile were analyzed. Coordinate measuring principle of parallel line laser detector array was given and photoelectric detection circuit with brief and high reliability was designed. Adjustment method of circuit sensitivity was derived and data acquisition was verified by experiment. The results show that this acquisition system is easy to install and debug, and has high functionality reliability. Acquisition speed and storing velocity can meet the demand of barrage weapons dispersion measuerment.
