Problems solved by technology

[0002] Deformation measurement plays a key role in the use and maintenance of weapons and equipment. The existing network camera deformation measurement method cannot meet the high dynamic measurement requirements. However, the use of fiber grating sensors for deformation measurement needs to solve the problem of cross-sensitivity between strain and temperature. It is only in the stage of laboratory verification, and there is still a big gap from the actual application

Abstract

The invention provides a ground-based differential interference radar deformation measurement method for complex environment based on artificial intelligence. The method comprises the following subsystems: an intelligent machine, a signal generator, a signal receiving terminal, a radar cable and a modem, wherein the signal generator is used for generating a specific pseudo-random code carrier signal; the intelligent machine is attached to each part of the surface of mobile equipment through an adhesive, and is used for receiving a pseudo-random code carrier signal sent by the signal generator, adding own ID identification information into the original carrier signal and then sending the pseudo-random code carrier signal in a radio wave form; and the signal receiving terminal is used for receiving the carrier signal transmitted by an antenna of the intelligent machine. The method has the advantages of real-time performance, expandability, low cost and the like; and the method is suitable for high-precision measurement of a wing curved surface in a wind tunnel and is also suitable for dynamic tracking measurement under actual test flight conditions.

Description

technical field [0001] The invention relates to the technical field of radar deformation measurement, in particular to a ground-based differential interference radar deformation measurement method for complex environments based on artificial intelligence. Background technique [0002] Deformation measurement plays a key role in the use and maintenance of weapons and equipment. The existing network camera deformation measurement method cannot meet the high dynamic measurement requirements. However, the use of fiber grating sensors for deformation measurement needs to solve the problem of cross-sensitivity between strain and temperature. It is only in the stage of laboratory verification, and there is still a big gap from the actual application. In the future, the demand for deformation measurement in complex environments such as aircraft wings and ship hulls will become more and more urgent. Designing a flexible skin antenna to achieve high dynamic deformation measurement in ...
