Embodiment 1

[0038] The composition of the airborne laser communication system capture simulation device provided by the present invention is as follows:

[0039] 1. As shown in Figure 1, the airborne optical communication capture device provided by the present invention consists of the first GPS antenna 1, theodolite 2, laser device 10, gyroscope 3, radio station and antenna 4, the second GPS antenna 5, support 6, pitch turntable 7. Rolling turntable 8 and heading turntable 9 constitute.

[0040] The first GPS antenna 1, the second GPS antenna 5, the theodolite 2, the laser 10, the gyroscope 3, the radio station and the antenna 4 are sequentially placed on the support 6, respectively fixed and rigidly connected. The pitch turntable 7, the roll turntable 8, and the heading turntable 9 are fixedly connected together, and the bracket 6 is fixed on the pitch turntable 7 to maintain a rigid connection.

[0041] The first GPS antenna 1 is used as the main antenna and as the origin of coordinat...

Abstract

The invention provides a capturing simulator in an airborne laser communication system, which is composed of a GPS aerial (1), a theodolite (2), an optical maser (10), a gyroscope (3) radio station and an aerial (40), a GPS aerial (5), a supporting stand (6), a pitching swivel table (7), a barrel roll swivel table (8) and a course swivel table (9), the device can realize plane visual axis north pointing alignment calibration under the dynamic static condition and is suitable for checking different machine types, waste of huge financial resources and materials which is produced by looming flight experiment checks is avoided, and simultaneously since all verification procedures are finished on ground, the safety is increased greatly. The size of capturing uncertain region can be confirmed tobe 35mrad through comparing the size of a communication visual axis rotary azimuth angle which is resolved out by a coordinate turning process and a pitching angle with the pitching angle and the azimuth angle of theodolite rotation and simultaneously the size of an angle of rotation and the direction of rotation process are confirmed to be correct. The system can realize perfect alignment of thevisual axis through a 3*3 scanning matrix.

Description

technical field [0001] The invention relates to a capture simulation device for an airborne laser communication system, and belongs to the technical field of laser communication. technical background [0002] The laser communication system uses laser as the information carrier. The high coherence and spatial orientation of laser determine that space laser communication has obvious advantages in many aspects compared with RF communication: strong anti-interference ability, good safety, small size and light weight of equipment , Unregulated spectrum, low power consumption, strong system mobility, low cost, transparent transmission protocol, etc. The laser communication system communicates point-to-point. Before communication, it is necessary to point the two communication boresights to the uncertain area, and then realize the precise alignment of the two communication boresights through antenna scanning technology. This is the capture process. Therefore, in the actual work pr...
