To effectively evaluate the damage efficiency of the terminal-sensitive projectile to the ground target under the power of multiple projectiles, this paper proposes a new method to calculate the damaging effect of the ground target by dividing the falling multiple sensitive projectiles into a multi-layer plane, uses the superposition principle to set up the multiple projectile power situation and analyzes the distribution of projectiles falling near the ground. The paper researches the detection method of the terminal-sensitive projectile with laser and infrared composite detection and establishes the calculation model of laser reflection echo power and thermal radiated power of the target. From the aspects of detection, attack and electronic jamming abilities, this paper set up the calculation model for multiple projectile power situation. Based on the distribution of the terminal-sensitive projectile group established, the fuzzy relationship between each evaluation index of the ground target and the distribution state of the terminal-sensitive missile group is used to establish the power evaluation function of the terminal-sensitive projectile. The analysis results demonstrate that the power of terminal-sensitive projectiles is related to the distance of the intersection of projectile and target, and when the intersection distance is small, the damaging effect of terminal-sensitive projectiles on the ground targets is better.

To scientifically evaluate the detection performance and detection ability of laser fuze, this study studies the double‐laser circumferential scanning detection method of laser fuze and its spatial‐temporal scanning detection model. According to the intersection relationship between projectile and target, the key parameters' calculation method of laser scanning detection is studied, and the spatial‐temporal scanning detection model and output signal model of laser fuze are established based on multi parameters in the detection system. Through calculation and analysis, the changing relationship between the laser detection ability under different laser beam incident angles, scanning frequency, deflection angle as well as other parameters and the laser echo under different deflection angles of laser fuze is discussed. The results show that when the emitted laser beam angle is fixed, the diameter of the detectable target becomes smaller and smaller with the increase of laser pulse frequency, that is, the detection ability of the laser fuze becomes higher and higher. At the same detection distance, the smaller the intersection angle of the missile and target, the stronger the laser echo power reflected by the target; when the detection distance and intersection angle increase, the detection probability of the laser detection system decreases significantly.
