Abstract

The invention relates to a target precise positioning device of a terahertz time-domain spectral scattering characteristic measurement system, which includes a horizontal electric shift table, a slide table, a scissor lift table, a pitch water shift table, an azimuth steering table, a low-scattering support and a one-way valve. The sliding platform is set on the horizontal electric moving platform, the scissor lifting platform is set on the sliding platform, the pitching water moving platform is set on the scissor lifting platform, the azimuth steering platform is set on the pitching water moving platform, and the low scattering bracket is set on the azimuth steering On the platform, the one-way valve is connected to the pitching water transfer platform. The present invention has the ability to accurately locate the five-dimensional target in the lateral direction, vertical direction, pitch direction, azimuth direction, and roll direction, which greatly reduces the target positioning error and improves the accuracy. Advantages of Hertz time-domain spectroscopic scatterometry systems for test accuracy.

Description

technical field [0001] The invention relates to the technical field of accurate target positioning, in particular to a target precise positioning device for a terahertz time-domain spectral scattering characteristic measurement system. Background technique [0002] In the terahertz time-domain spectral scattering characteristic measurement system, due to the excellent directivity of the terahertz beam and the dominance of the image scattering echo in the scattered echo of the target, the measurement error of the radar cross section of the target is largely caused by the positioning error of the target Decide. Therefore, the precise positioning of the target has become the key technology of the terahertz time-domain spectral target scattering measurement. [0003] In the existing target positioning methods, the turntable and the manual pitch adjustment device are generally used to support the low-scattering bracket. The target control dimension is small, the efficiency is lo...
