Abstract

The invention discloses a multi-platform heading attitude determination method of a communication antenna in motion based on transfer alignment. The method installs the inertial measurement unit on the antenna in motion and performs multi-platform navigation calculation, and uses the output information of the navigation equipment on the antenna installation carrier and the transfer alignment algorithm to compensate the error of the strapdown navigation algorithm result of the inertial measurement unit. Finally, the multi-platform attitude data validity evaluation method is used to obtain the attitude information that is beneficial to the antenna to improve the tracking performance. The present invention combines the antenna azimuth angle and signal strength information to establish a multi-platform heading attitude determination method to improve the tracking performance of the antenna, and has the advantages of no need for human operation, simple implementation and wide application range.

Description

technical field

[0001] The invention belongs to the technical field of antennas, and in particular relates to a novel method for determining the attitude of an antenna in motion. Background technique

[0002] With the development of communication measurement and control, the application market of antennas has expanded, and in most applications, it is required to achieve precise measurement and control of antenna pointing. In particular, in the fields of vehicle-mounted, ship-mounted, and airborne satellite communications in motion, most antenna installation carriers have relatively accurate navigation equipment such as inertial navigation systems, which are used to measure the attitude information of the carrier, and can also Provided to the antenna to compensate for the pointing angle deviation caused by the movement of the carrier. In the prior art, the antenna directly uses the attitude information of the carrier, and there are the following problems:

[0003] a) The up...
