Method for simultaneously measuring smoke screen attenuation rate and radiation intensity

Abstract

The invention relates to a method for simultaneously measuring smoke screen attenuation rate and radiation intensity. The method is characterized in that when a smoke screen is not released, the environment radiation intensity and the atmosphere attenuation coefficient can be measured by blackbodies and infrared detectors; and when the smoke screen is released, the smoke screen attenuation rate for shielding the blackbodies and the infrared radiation intensity are simultaneously measured based on the environment radiation intensity and the atmosphere attenuation coefficient. According to the method, the multi-point smoke screen attenuation rate and radiation intensity can be measured through the arrangement of a plurality of infrared detectors.

Description

technical field [0001] The invention relates to a method for simultaneously measuring smoke screen attenuation rate and radiation intensity. Background technique [0002] Smoke screen is an important means of photoelectric countermeasures, and its shielding effect on infrared targets is an important basis for evaluating its jamming performance. The main mechanism for the smoke screen to cover the target is to attenuate the target infrared radiation on the infrared detector through the scattering effect of the smoke screen. In addition, the infrared radiation of the smoke screen itself, the ambient infrared radiation reflected by the smoke screen, and the ambient radiation will also cause a decrease in the contrast of the infrared image. [0003] Usually, the attenuation rate of smoke screen to infrared radiation is used to evaluate the quality of smoke screen shielding performance. In the battlefield environment, if the infrared radiation of the smoke screen itself is too ...

Problems solved by technology

Among them, the advantage of the laser measurement method is that it is less affected by environmental radiation. The disadvantage is that it can only measure the infrared radiation attenuation rate of the smoke screen on a specific spectral line. The infrared radiation attenuation rate in the infrared detection band must be extrapolated based on empirical formulas. The empirical formula should be selected according to the change of the smoke screen formula

The advantage of the infrared thermal imager measurement method is that it can directly measure the infrared radiation attenuation rate of the smoke screen in the medium-wave or long-wave band, but it is easily affected by environmental radiation when measuring in the field

[0005] At present, the methods mentioned in the literature discussing the smoke attenuation rate cannot simultaneously measure the smoke attenuation rate and the infrared radiation intensity of the smoke screen itself.
