Abstract

The invention discloses a radar antenna azimuth rotary table, and relates to the technical field of radar. The rotary table comprises an upper position rotary table, a middle pitching mechanism and alower position rotary table, wherein the lower position rotary table comprises a first gearbox and a first rotary table; the middle pitching mechanism comprises a bottom plate, a supporting side plate, a motor, a first rotating shaft, a driving gear, a driven half gear and a second rotating shaft; the upper positioning rotary table comprises a second gearbox, a second rotary table and an adjustinghandle. 360-degree dead-corner-free rotation is achieved through the upper rotary table and the lower rotary table, different control precision and adjusting handles are adopted for the two rotary tables, various experiments can be conveniently conducted on the antenna orientation, the pitch angle of the middle pitching mechanism exceeds 145 degrees, and the requirements of radar antenna experiments can be met.

Description

Technical field [0001] The invention belongs to the technical field of radar, and particularly relates to a radar antenna azimuth turntable, more specifically, a radar antenna azimuth turntable for testing. Background technique [0002] As a replay device in the test of related performance parameters of the antenna, the antenna test turntable is mainly used to support the weight of the antenna and control its movement, provide the required movement mode for the antenna, and give the position signal of the antenna through the angle measuring element. At the same time, data collection and analysis are performed on the tested antenna, so as to achieve the purpose of antenna performance test. In the early days when the antenna was used by people, its related parameters were low, which directly caused the performance parameters of the turntable to not be very high. Obviously, this is easier to achieve for mechanical and electrical control requirements. Then, based on the progress of ...
