“…By measuring the time that the projectile reaching each light-screen and combining with the known spatial structure of the light-screen array, the coordinates of the projectiles are measured [8][9]. The measurement results are influenced by combined effect by the calibration errors of spatial structure the light-screen array [10], the time extraction errors of the projectile reaching the light-screens [11] and so on.…”

The light-screen array measurement method is very suitable for measuring the coordinates of rapid-fire weapons, and the measurement error is determined by the measurement model. In this paper, the separated light-screen array is improved to an integrated light-screen array, which reduces the parameters and optimizes the measurement model. Three kinds of factors affecting the coordinate measurement error of the projectile under the integrated measurement model are analysed, and the influence of the factors on the distribution of coordinate measurement errors is simulated and analysed in the selected 1m×1m target area. Then the error distribution of the separated measurement model and the integrated measurement model is simulated and analysed under the same conditions based on the design values and current technology level. The result shows that compared with the separated measurement model under the same simulation conditions, the comprehensive coordinate measurement error is optimized by about 2.1mm within 1m×1m target area. The research can provide reference for the design and optimization of light-screen array and other similar photoelectric measurement systems, and provide new ideas for improving the coordinate measurement precision of therapid-fire weapons.

For the moving state of armored vehicle, the random rendezvous of rotary scanning optical imaging system and armored vehicle will be in an uncertain state, which makes the target information detected by the system floated and the reliable target signal hardly obtain. In this article, the target detection radiation characteristic distribution of the system and the calculation method of the geometric parameters of optical scanning in the random rendezvous state are obtained. An optical scanning detection calculation method for air‐ground armored targets is presented under space‐time correlation condition. According to the characteristic of rotary scanning optical imaging system caused by the thermal radiation of armored vehicles, a model of infrared radiation characteristic distribution of armored vehicles is established form the relationship between the system and armored targets. Combining with the established air‐ground rotation optical imaging‐scanning model, the contribution of Infrared Radiation to the optical imaging sensor during the movement of armored vehicles in different states and the calculation function of the output signal of the sensor are given respectively. Through calculation and experiment, it is found that the armored targets can be effectively detected within detection zone that the detection height is less than 35 m, the area of the radiation characteristic area is more than 1 m2 and the detection angle is 20 ° : 40°. The moving direction and contour size of the target can be distinguished by the rendezvous angle difference and the response time of the signal response time of the central.
