Active target device with infrared tracking and beacon light pointing functions

Abstract

The invention discloses an active target device with infrared tracking and beacon light pointing functions, belongs to the technical field of mechanical engineering, and aims to solve the technical problem that in the prior art, active beacon light with the farthest distance of 2 meters cannot be emitted under the airborne condition. The device comprises an infrared tracking unit, beacon light pointing units, a self-calibration light path, an installation frame and a shock absorber, the infrared tracking unit is fixed under the installation frame, the beacon light pointing units are fixed at the left end and the right end of the installation frame, and the self-calibration light path is installed in the infrared tracking unit and the installation frame. The lower end of the shock absorber is connected with the upper end of the mounting frame, and the shock absorber is connected with an airplane; after finding the host, the infrared tracking unit tracks the host and transmits position information to the beacon light pointing unit, and the beacon light pointing unit transmits beacon light to the host according to the transmitted information. According to the invention, the tracking turntable with an infrared detection function is adopted to realize tracking, and the pointing function to the host is realized according to the information of the infrared tracking turntable.

Description

technical field [0001] The invention relates to an active target device with functions of infrared tracking and beacon light pointing, and belongs to the field of mechanical engineering. Background technique [0002] The infrared tracking and beacon light pointing function device provides five channels of beacon light for the host with a maximum distance of 2 meters and a parallelism better than 0.3°. The device mainly completes the capture and stable tracking of the host under airborne conditions. After successful tracking, actively pointing beacon lights are emitted to provide the host with a set of five real-time actively pointing beacon lights. [0003] The solution needs to meet the tracking under all-day conditions, and the device needs to have the infrared tracking function. The existing technical solution of infrared tracking and beacon light emission is integrated in the tracking turntable, which cannot meet the requirement of a maximum distance of 2 meters for the ...
