Device and method for measuring infrared transmittance of infrared interference smoke screen in vacuum

Abstract

The invention discloses a device and a method for measuring infrared transmittance of an infrared interference smoke screen in vacuum. The device for measuring the infrared transmittance comprises a vacuum tank, a vacuum smoke formation chamber, a pipeline, a vacuum pump, a filter and a glass fiber filter membrane, wherein the vacuum smoke formation chamber is fixedly arranged on the surface of the outside of the vacuum tank, the vacuum smoke formation chamber is communicated with the vacuum tank, and the glass fiber filter membrane is arranged at the joint between the vacuum smoke formation chamber and the vacuum tank; the vacuum tank and the vacuum pump are connected through the pipeline, and the filter is arranged at the joint between the pipeline and the vacuum pump; the vacuum pump is used for adjusting the vacuum degree in the vacuum tank; an ignition device is arranged in the vacuum smoke formation chamber and used for igniting an infrared interference smoke screen producing agent to generate the infrared interference smoke screen. The device and the method for measuring the infrared transmittance can be used for testing the infrared transmittance of the infrared interference smoke screen in the specific granularity interval.

Description

Technical field [0001] The invention relates to the technical field of infrared interference smoke screen effect detection, in particular to a vacuum mid-infrared interference smoke screen infrared transmittance measurement device and method. Background technique [0002] Infrared jamming smoke screen is an important stealth jamming method on the main battlefield of the atmosphere. Similarly, infrared jamming smoke screens can also be used for infrared stealth jamming of outer space battlefield targets, that is, throwing infrared jamming materials on the path between the target and the incoming missile or the sighting detection light to form an infrared jamming smoke screen, using infrared jamming to extinction the target's infrared radiation To achieve the purpose of infrared stealth interference. The outer space is a vacuum microgravity environment with no air. The "interference cloud" formed by the infrared interference smoke screen as the infrared interference material is no...
