Embodiment Construction

[0052] Such as Figure 1-5 As shown, the UAV-based large-scale parabolic antenna surface accuracy test system consists of two parts: the detection part and the data processing part, which are connected in sequence:

[0053] The detection part consists of a multi-axis drone equipped with a camera, identification marks pasted on the surface of the antenna, a laser calibration reference subsystem, and a signal receiving and transmitting module I;

[0054] A. The multi-axis drone aircraft and its equipped camera constitute the shooting subsystem. The multi-axis aircraft is a six-axis aircraft, and then the camera is hung. The camera integrates a memory card to back up and store the captured pictures;

[0055] At the same time, the UAV carries the signal receiving and transmitting module Ⅰ, which is connected to the camera and the flight control circuit of the UAV. This module uses wireless frequencies such as wifi, 3G or 4G to transmit and receive; it is used to modulate the image...

Abstract

The invention discloses an unmanned plane-based large-scale parabolic antenna surface precision test system, which comprises a detection part and a data processing part. The detection part and the data processing part are sequentially connected. The detection part comprises an unmanned plane with a camera, an identification mark, a laser calibration reference subsystem and a signal receiving and transmitting module I. The data processing part comprise a signal receiving and transmitting module II and a computer. By adopting the system, a camera probe arranged on the unmanned plane is used forshooting the identification mark on the surface of an antenna, so that the current panel accuracy of the antenna can be rapidly and accurately obtained in real time at different observation angles ofthe antenna. Meanwhile, the performance of the antenna can be rapidly improved through rapidly correcting the surface type of the antenna. The problems in the prior art that the pitching angle is considered and the light is polluted during the current mainstream antenna surface type measurement process can be overcome.

Description

technical field [0001] The invention relates to the fields of large-scale parabolic antenna measurement and radio astronomy research, and is suitable for real-time evaluation of antenna performance when the large-scale parabolic antenna is used for radio astronomy observation, so as to obtain the current antenna performance. Background technique [0002] With the development of science and technology, large parabolic antennas have been applied to many aspects such as ground communication antennas, space-borne deployable antennas, and radio astronomy telescopes. Beam, high efficiency, etc., which will inevitably increase the difficulty of electromagnetic design and structural design of the parabolic antenna. Reflector antennas usually work in a higher frequency band. In order to pursue higher electrical performance indicators, higher requirements are placed on the accuracy of the antenna structure; therefore, it is necessary to quantitatively describe the influence of various...
