Embodiment Construction

[0021]The specific embodiments of the present invention will be further described below in conjunction with the drawings.

[0022]The principle of the present invention is as follows: The principle diagram of mixing angle adjustment is as follows:figure 1 As shown, where o is the azimuth rotation center of the turntable, ∠a is the horizontal angle of the sliding pole (variable angle), ∠b is the angle between the sliding pole and the radome and antenna mounting assembly pole (variable angle), ∠ c is the elevation angle of the antenna radome (variable angle). The adjustment of the pitch angle, ∠a∠b can change the angle of ∠c even more to change the pitch angle of the radome and antenna.

[0023]The radome test turntable of the present invention includes a turntable azimuth rotation structure, a horizontal strut longitudinal movement structure, a pitch angle conversion and longitudinal sliding structure, a radome and antenna installation positioning component structure, and a turntable contr...

Abstract

The invention belongs to the design field of the radome electrical performance test rotary table, and relates to a radome test rotary table. The radome test rotary table comprises a rotary table direction rotation structure and a horizontal strut longitudinal movement structure, a pitching angle conversion and longitudinal sliding structure, a radome and antenna mounting positioning assembly structure, and a rotary table controller. The test rotary table simplifies mounting demands on the test rotary by various different and small shaped radomes, the requirements on the test function, the testrange, and the test technology by majority of small shaped radomes at present can be satisfied, and the test rotary table universality is improved.

Description

Technical field[0001]The invention belongs to the design field of a radome electrical performance test turntable, and relates to a radome test turntable.Background technique[0002]At present, small radome test turntables mainly have two structures: side-arm type and double-arm type. Most of the turntables of these two structures are designed with mounting rings to complete the installation of the radome. However, in actual use, the structure is bulky and the installation A series of problems such as inconvenient debugging, large reflection of microwave signals, and too many fixtures. As far as the shape diversity and variety of current small radomes are concerned, the original turntables with side-arm and double-straight-arm structures can no longer meet the current test requirements.Summary of the invention[0003]The technical problem to be solved by the present invention is to provide a universal test turntable suitable for various small and special-shaped radomes, which can simplif...
