Pitch angle adjusting device of synthetic aperture radar

Abstract

The invention discloses a pitch angle adjusting device of a synthetic aperture radar. The pitch angle adjusting device comprises two symmetrical supporting plates and a connecting plate arranged between the two support plates and fixedly connected with the two supporting plates, a motor is fixedly mounted on the upper end surface of the upper one of the two supporting plates, the motor is connected with a threaded rotating shaft rotationally arranged in the lower supporting plate through a motor shaft, a lifting block with one side abutting against the connecting plate is installed on the outer edge face of the threaded rotating shaft in a threaded fit mode, a detection device is detachably installed on one side of the lifting block, and the detection device comprises two symmetrical U-shaped side plates and an angle scale arranged on one side of one U-shaped side plate. The pitch angle adjusting device of the synthetic aperture radar is reasonable in structure, the position of the radar can be conveniently adjusted, the monitoring range is enlarged, meanwhile, the current angle condition can be conveniently and visually known, accurate adjustment is facilitated, and the practicability is high.

Description

technical field [0001] The invention belongs to the technical field of radar pitch angle adjustment devices, and in particular relates to a pitch angle adjustment device of a synthetic aperture radar. Background technique [0002] Synthetic aperture radar is a high-resolution imaging radar, which can obtain high-resolution radar images similar to optical photography under weather conditions with extremely low visibility. The radar that uses the relative motion of the radar and the target to synthesize a larger equivalent antenna aperture from a smaller real antenna aperture by data processing is also called synthetic aperture radar. Synthetic aperture radar is characterized by high resolution, can work around the clock, and can effectively identify camouflage and penetrate cover. [0003] At present, when the distance is measured by synthetic aperture radar, in order to obtain more accurate data, it is usually necessary to adjust the pitch angle of synthetic aperture radar,...

AI Technical Summary

Problems solved by technology

[0003] At present, when the distance is measured by synthetic aperture radar, in order to obtain more accurate data, it is usually necessary to adjust the pitch angle of synthetic aperture radar, but the existing adjustment device is not convenient to adjust the position of synthetic aperture radar, which limits its The range of monitoring, and the existing adjustment device is inconvenient to intuitively understand the current angle situation in the process of adjusting the pitch angle of the synthetic aperture radar, which is not conducive to precise adjustment
