Description

The invention relates to the field of application of optoelectronic devices, namely, to the field of lighting devices for illuminating optoelectronic devices of small-sized unmanned aerial vehicles (MBLA), can be used in military equipment.

Various technical solutions are known for providing individual protection of objects in the optical range of electromagnetic waves using illumination from aiming and pointing devices, such as missiles with infrared homing guided missiles, based on the creation of special active interference devices operating in the infrared (IR) frequency range radiation spectra (patent RU No. 2347720).

A disadvantage of the known personal protection systems is the complexity of their implementation and the predominant possibility of use only when protecting against air defense systems controlled by ground-based radar stations. In addition, well-known systems cannot be used for individual protection of objects from MBLA, equipped with optoelectronic devices operating in the frequency range of ultraviolet, visible and IR radiation spectra.

The invention is the use of a high-power searchlight, analogue, RU patent No. 2477553, producing a dazzling effect on MBLA reconnaissance devices, the spatial coordinates of which are determined by the prototype of RU patents No. 2123165, No. 126846 in the entire optical range of electromagnetic waves, FIG. one.

The invention The method for illuminating optical-electronic devices of small-sized unmanned aerial vehicles operates according to the following scheme: electromagnetic radiation from MBLA 1 propagates in the atmosphere, is determined by a detection unit and an automated information processing system (BIOASOI) 2, and transmits a signal to a laser radiation source, FIG. 1. BOIASOI allows you to calculate the power of laser radiation, the area of the light screen and adjust the movement of the light screen in space.

Laser light source 3 generates radiation of a certain wave (the wavelength can vary) in the direction of MBLA using an electron-mirror guidance system 4, which has electric drives 6 that change the position of the mirror in two planes, and a drive that changes the position of the mirror relative to the axis of guidance on MBLA. The power supply unit is powered by the entire system 5. Laser radiation illuminates the optoelectronic intelligence devices MBLA in the entire optical range of electromagnetic waves. The number of radiation sources 7 can be from one or more, depending on the area of the object of protection and the possible location of the MBLA 8, providing a total area of exposure of 9 MBLA, FIG. 2.

In FIG. 1 and 2 are indicated:

1 - MBLA;

2 - block detection and automated information processing system;

3 - a source of laser radiation;

4 - electron-mirror guidance system;

5 - power supply;

6 - electric drives;

7 - a variant of the placement of radiation sources;

8 - possible places of occurrence of MBLA;

9 - the total area of exposure to sources of laser radiation.

The use of laser radiation aimed at MBLA observation devices, both electron-optical and optical, greatly reduces the detection efficiency of objects and destroys the electronic matrices of receiving devices.
