the fourth and fifth outputs of the control and processing unit 6, respectively.

In this case, the first 7 and second 8 optical quantum generators with the first 9 and second 10 mirrors are spaced relative to each other, and the studied antenna 4, the antenna of the reference channel 5 and the auxiliary antenna 1 are placed between them.

The optomechanical units 13 and 14 consist of bases 19 and 20, mounted on the output shafts of the drives 15 and 17, for example, electric motors. Moreover, the flat mirrors 9 and 10 are kinematically coupled to the drives 16 and 18 and mounted on the bases 19 and 20.

Drives 15 and 17 provide scanning of mirrors 9 and 10 in the azimuthal plane, and drives 16 and 18 in the elevation plane.

The control and processing unit 6 consists of an input and output information device 21 (UVV), a computer 22, for example, DVK-2, two interfaces 23 and 24, which ensure the output of the computer 22 is matched with the inputs of the drives 15, 16 and 17, 18. To start an auxiliary transmitting antenna 1 generator 2 and optical quantum generators 7 and 8, an electronic switch 25 is installed in the control and processing unit 6.

In the control and processing unit 6 there is a recorder 26 for documenting the position of the plasma probe.

The information input and output device 21 is controlled by an operator.

A plasma probe is formed by introducing two (or more beams of radiation from optical quantum generators at one point in space).

The device operates as follows.

At the initial moment of time, the operator gives a command through the air-blast 21, calculator 22. Interfaces 23 and 24 to the drives 15, 16 and 17 "18 for installing the rays of optical quantum generators 7 and 8 at a given point in space. After installing the rays of the optical quantum generators 7 and 8, the operator sends a command through the air-blast 21, calculator 22, interface 23, electronic switch 25 to start the generator 2, which generates microwave signals transmitted through an auxiliary transmitting antenna 1 in the direction of the plasma probe. At the same time, the command to start the optical quantum generators 7 and 8 is received through the air-blast 21, calculator 22, interface 23, electronic switch 25 and outputs 4, 5 of the control and processing unit 6. At a given distance R from the measured antenna 4

a probe plasma is formed in space. The microwave signal reflected from the plasma probe enters the antenna of the reference channel 5 and the measured antenna 4, the output of which

microwave signals are fed to the signal ratio meter 3 and then to the control and processing unit 6 for fixing on the recorder 26. The plasma probe moves according to a given program (for example, only in

elevation plane, although any variant of the probe-plasma motion over the surface of an imaginary sphere with a constant radius is possible). The operation of all elements included in the system when moving the probe-plasma is carried out by the above method. The position angles of the plasma probe in the space "and / are set using the control and processing unit 6 and are recorded on the recorder 26,

for example, a magnetic disk or plotter. Also, information about elevation angle and azimuth is received at the recorders 26, under which a probe plasma is observed with respect to the electric center of measurement in -.
