Embodiment Construction

[0021] The specific embodiments of the present invention will be further described below in conjunction with the accompanying 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 (variable angle) of the sliding support rod, ∠b is the included angle (variable angle) between the sliding support rod, the radome and the antenna mounting component support rod, ∠ c is the antenna pitch angle radome pitch angle (variable angle). The adjustment of the pitch angle, ∠a∠b can change the angle of ∠c to a greater extent to change the pitch angle of the radome and the antenna.

[0023] The radome test turntable of the present invention includes a turntable azimuth rotation structure, a horizontal support rod longitudinal movement structure, a pitch angle conversion and longitudinal sliding structure, a rado...

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, the small radome test turntable mainly has two structures: side arm type and double arm type. Most of the turntables of these two structures are designed with a mounting ring to complete the installation of the radome. However, in actual use, the structure is heavy and difficult to install. Inconvenient debugging, large microwave signal reflection, too many fixtures and other problems. In terms of the variety of shapes and types of various small radomes, the original side arm type and double straight arm type turntables can no longer meet the current testing requirements. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a universal test turntable suitable for all kinds of small special-shaped radomes, which can simplif...
