Wireless laser communication reflection type aiming tracking system and laser aiming tracking method

Abstract

The invention discloses a wireless laser communication reflection type aiming tracking system and a laser aiming tracking method. A controller is controlled to control pitch and horizontal motion of atwo-dimensional rotating reflection mirror; a laser transmitted by the wireless laser communication transmitting end is reflected into an optical receiving antenna; the optical receiving antenna focus the later into a small facula, and the small facula hits a four-quadrant detectorin the optical receiving antenna; the four-quadrant detector output corresponding voltage to a control processor, andthe control processor controls pitch and horizontal motion of the reflection mirror based on the received voltage until the facula hits in a small hole at the center of the four-quadrant detector; acoupling fiber is fixed to the center through hole of the four-quadrant detector, and when the facula enters the center through hole, a laser signal transmitted by the transmitting end can be coupledinto the fiber; and the fiber is used for transmitting the laser signal to sequential signal processing portion, and establishment of wireless laser communication link is achieved. The aim of the APTsystem establishes the wireless laser communication link in a short time is achieved.

Description

technical field [0001] The invention belongs to the technical field of wireless laser communication, and in particular relates to a fast-deployable wireless laser communication capture, alignment and tracking method and system. Background technique [0002] Wireless laser communication has many advantages, such as huge communication capacity, fast transmission rate, strong anti-interference ability, good concealment, and no need for spectrum license. It is one of the most advanced communication solutions, and it has also been widely used in various fields, especially in the military field. Traditional radio communications are vulnerable to eavesdropping and jamming, which has a huge impact on military operations. Wireless laser communication technology combined with other communication methods can effectively solve the above problems, so all countries are scrambling to study the application of wireless laser communication in military affairs.
