Aerial stealth surveillance radar

Claims

1. An aircraft radar for covert surveillance of the surrounding environment, comprising a receiving antenna array, the elements of which are connected by optical channels to a digital information processing unit, characterized in that the elements of the antenna array are made in the form of electric vibrators, connected to each other by means of dielectric mechanical connections in a flexible thread located in the oncoming air flow, and connected to corresponding radio receivers located on the aircraft by means of feeders made in the form of dielectric light guides that enter into optical contact with semiconductor diodes included in the break in the wire of the corresponding vibrators.

2. An aviation radar according to paragraph 1, characterized in that two semiconductor diodes are connected in parallel in mutually opposite directions in the break in the wire of the electric vibrator.

3. An aircraft radar according to claim 1, characterized in that the output end of said optical waveguide comes into optical contact with a semiconductor diode electrically connected to the input of the corresponding receiver.

4. An aviation radar according to paragraph 1, characterized in that each of the said light guides is also connected at the output end to an adjustable light source, which serves to create a bias current in the diodes.

5. An aircraft radar according to paragraph 1, characterized in that several of the said threads with chains of electric vibrators are attached to the aircraft, forming a two-dimensional or spatial antenna array.

6. An aircraft radar according to paragraph 5, characterized in that the line of attachment of the electric vibrator threads has an arcuate bend in a direction perpendicular to the longitudinal axis of the aircraft.

7. An aircraft radar according to paragraph 1, characterized in that it has a synthetic aperture formed by the said threads with electric vibrators located on two or more aircraft equipped with a coordinated navigation system.
