Abstract

The invention provides a testing method used for evaluating the visible light smoke screen shadowing effect and belongs to the technical field of modern smoke screens. The method is used for detecting whether a smoke screen forms effective shadowing and detecting smoke screen duration, smoke screen effective size and other efficacy parameters. A marker post serves as a background reference. A marker post spectrum image penetrating through the smoke screen is collected by means of an acousto-optic turnable filter (AOTF) spectrum imaging instrument; a data processing terminal conducts weighted synthesizing on the collected spectrum image to obtain a true color image based on human eye thresholds, and the true color image is compared with a non-smoke-screen-shadowing true color image collected before smoke screen releasing to evaluate whether the smoke screen forms effective shadowing or not; according to the formula in the description, the size of the smoke screen is measured; the smoke screen formation time is measured according to the whole shooting process of the spectrum imaging instrument. Compared with the prior art, the method has the advantages of being simple in calculation, easy to operate, capable of saving time and labor and high in efficiency.

Description

technical field

[0001] The invention belongs to the technical field of modern smoke screens, in particular to a test method for evaluating the shading effect of visible light smoke screens. Background technique

[0002] Smoke screen is an effective photoelectric passive jammer, which can make photoelectric scanning, tracking equipment and precision-guided weapons lose track and attack targets by shielding interference. Since the 1960s, many countries have successively used various types of jamming bombs, smoke bombs, smoke bombs, etc. to equip their troops, and almost all modern tanks and armored vehicles are equipped with launchers. Under the condition of not destroying the power system, it can prevent the normal and effective effect of the instrument on the electromagnetic spectrum, blind the enemy's reconnaissance and guidance radar, cause the radio command system to fail, and soldiers cannot accurately observe the target.

[0003] In modern warfare, with the successful ...
