Description

The invention relates to devices for radar masking of spacecraft (SC) in unsupported space.

There are various methods and devices that make it difficult to recognize (identify) objects according to estimates of characteristics and effective dispersion surface (EPR) - changes in their EPR during the flight:

radar absorbing coatings;

plasma formations;

transformable rigid and inflatable structures;

towed, associated with the aircraft, and autonomous false targets (simulating spacecraft).

As analogues of devices, target recognition methods, patents are considered: 2393420, C2, RU, 2006; 4,414,339 G21F / 10, US; 4,865,328 F41J 9/08, US; 3,774,208 NKI-N4D, US; 3371345 NCI 343/18, US; 2134740 N4D, W / Britain.

The purpose of the invention is the creation of a fluctuating false target that mimics a complex object that is difficult to recognize.

As a prototype, an application for invention No.2000110269 / 09 is proposed, according to which a false target is formed inside an inflatable shell (in the simplest form in the form of a ball) due to the fact that the elements of the transformed corner reflector are attached to the inner surface of the shell in such a way that a rigid the design of the corner reflector inside the shell (sphere or other shape) after its full disclosure.

The proposed device is an inflatable false target in an unsupported space - is implemented by forming a shell (for example, from Mylar) due to the residual gas inside it when throwing the folded false target into space.

The purpose of the proposed technical solution - the formation (creation) of a complex fluctuating object - is achieved by the fact that inside the Mylar shell there is a gas generator block with a fuse and a current source with a switch held inside the formed shell by flexible elastic bonds of a limited length, fixed at one end to the inner surface of the shell, and the other to a gas generator unit with a current source and a switch, one of the elastic links being fixed to the current source switch.

In one of the diametrical planes of the section of the shell in the walls of the shell, local thickenings are made with openings-channels through which the internal volume of the shell communicates with the external environment. The holes are equipped with nipple devices that hold the pressure of the residual gas in the shell and are triggered when the pressure rises after the gas generator (smoke bomb) is activated (activated).

Hole channels in the thickenings of the shell are directed in one direction - clockwise or counterclockwise.

When the gas generator is operating, the pressure in the shell rises to the level at which the outflow of gas (gas mixture) through the nipple devices occurs. As a result, the shell is given a rotational movement.

The outer surface is fragmentary made with different reflective characteristics, and during rotation a complex fluctuating object is realized, thereby complicating the identification of both the masked object and the local target itself.

The inflatable false target contains: an inflatable shell 1, thickenings 2 with channel holes 3, nipple devices 4, a gas generator 5 with a fuse 6, a current source 7 with a switch 8, flexible elastic bonds of a limited length 9.

In this case, a gas generator with a fuse, electrically connected with it, and a current source with a switch are made in the form of a block.

The device is a false target - it works as follows.

A complex false target is pushed out (thrown out) from a masked space object. The shell 1 in the unsupported space under the influence of the residual gas expands and takes a given geometric shape, while due to flexible elastic bonds of a limited length 9, a generator 5 with an electric valve 6, a current source 7 with a switch 8 are hung out.

Simultaneously with the opening of the shell 1 and hanging inside the false target (shell) of the gas generator block with a current source from one of the flexible connections 6 fixed to the switch, the power source is activated, the igniter is activated and the gas generator is activated.

The pressure in the shell rises to the level of response of the nipple devices. Since the openings are directed clockwise or counterclockwise, the shell - the false target begins to rotate, and the various reflective characteristics of the surface elements create the effect of a complex fluctuating object. This provides a solution to the problem - recognition of both the masked space object and the most false target.
