Measuring system and method for shadowing effect of smoke screen on laser

Abstract

The invention discloses a measuring system and method for a shadowing effect of a smoke screen on laser. The measuring system comprises at least two laser transmitters, and a laser receiver which is used for receiving laser transmitted by the laser transmitters and for detecting an energy density value of the laser. The measuring system also comprises an industrial control computer which is connected with the laser receiver and is used for collecting the energy density value of the laser; the industrial control computer is used for processing data of the collected energy density value of the laser and acquiring a change rule with time of the transmittance through the smoke screen of the laser transmitted by the laser transmitters; according to the measuring method, the transmittance through the smoke screen of the laser is measured by the measuring system, and the transmittance through the smoke screen of more than two paths can be simultaneously measured. A plurality of laser transmitters are adopted for transmitting the laser, the laser irradiates at a plurality of positions on the smoke screen released at one time, and the transmittance through the smoke screen of the laser at the plurality of positions on the smoke screen can be measured, therefore, the confidence of a measurement result is effectively improved, and the measurement cost is saved.

Description

technical field [0001] The invention relates to the technical field of evaluating the laser shielding effect of a smoke screen, in particular to a measurement system and method for the laser shielding effect of a smoke screen. Background technique [0002] Because the laser is scattered, absorbed and attenuated when passing through the smoke screen, the smoke screen plays the role of blocking the laser and protecting the target. In modern battlefields, smoke screens are often used to form interference barriers to interfere with the enemy's laser weapons or photoelectric reconnaissance systems and protect us. Party goals and actions. Choose a smoke screen that has strong absorption and scattering capabilities for laser light, so that the attenuation rate of the laser through the smoke screen can reach 1, so that the laser seeker cannot receive the laser signal reflected from the target, and can only receive the laser signal from the smoke screen. The laser signal reflected o...

Problems solved by technology

This measurement method has the following disadvantages: First, the randomness of the measurement is large, and the characteristics of the smoke screen released each time are different. For example, the concentration of particles in the smoke screen released each time may be different, so the measurement results using a single laser Second, the cost-effectiveness ratio is low. This measurement method needs to release smoke screens many times, resulting in waste
