specific Embodiment

[0058] Use 7.62mm bullets to carry out live ammunition shooting, and detect the limit sensitivity of a certain type of canopy target.

[0059] The specific parameters of the sky screen target are shown in Table 1.

[0060] Table 1 Sky curtain target performance parameters

[0061]

[0062] The experimental parameters of the live ammunition shooting process are shown in Table 2.

[0063] Table 2 Experimental parameters

[0064]

[0065] Since the length of the projectile is greater than the thickness of the light curtain, the experimental parameters are substituted, and by calculation, the system parameter c=414, and the maximum detection distance is H max =4.3m, detection sensitivity s=562.

Abstract

The invention discloses a method for detecting the maximum detection distance and the ultimate sensitivity of a skyscreen target, and aims to solve the problem that an ultimate sensitivity model and a maximum detection distance model are incomplete and inaccurate in the prior art. According to the specific technical scheme, a system inherent parameter c is determined by means of the output voltage value of the sky screen target shot by a live bullet, and the maximum detection distance and the theoretical value of the limit sensitivity of the sky screen target can be rapidly and accurately obtained only by measuring the brightness received by the sky screen target on site and calculating the root-mean-square value of noise. According to the method, a theoretical guidance basis is provided for researchers for designing the skyscreen target, optimization design of the skyscreen target is facilitated, and meanwhile, a calculation basis is provided for personnel using the skyscreen target to carry out testing, so that use is convenient.

Description

technical field [0001] The invention belongs to the field of photoelectric testing of shooting ranges, and in particular relates to a detection method for the maximum detection distance and limit sensitivity of a sky screen target. Background technique [0002] The canopy target is an important test equipment for ballistic parameters outside the shooting range, and is widely used to measure the velocity of projectiles. The canopy target belongs to the photoelectric test equipment. During the test process, the changing luminous flux is converted into an electrical signal, and the change of the electrical signal is detected by the photoelectric tube. The signal processing method is used to extract the projectile passing time, and the projectile velocity is measured according to the principle of section speed measurement. . In the process of use, the ultimate sensitivity of the sky screen target (characterized by the number of multiple diameters) and the maximum detection dist...
