Large missile-borne radar radome erecting platform

Abstract

The invention provides a large missile-borne radar radome erecting platform. The platform comprises a lifting mechanism, a coarse adjustment mechanism matched with the lifting mechanism, a fine adjustment mechanism matched with the coarse adjustment mechanism and a mounting mechanism matched with the fine adjustment mechanism; a radome can be fixed to the mounting mechanism; the lifting mechanism can drive the coarse adjustment mechanism to change the height, the coarse adjustment mechanism can drive the fine adjustment mechanism to adjust the position in the horizontal plane, and the fine adjustment mechanism can drive the mounting mechanism to change the height. Rapid coarse adjustment of the position of the radome is achieved through the lifting mechanism and the coarse adjustment mechanism, the radome is moved to the designated position, then accurate adjustment of the position is conducted through the fine adjustment mechanism, the high-precision requirement for head cover matching can be met, the matched mounting mechanism can be replaced according to the type of the radome, the adaptability is high, and the equipment cost is obviously reduced.

Description

technical field [0001] The invention relates to the technical field of radar manufacturing, in particular to a platform for erecting a large missile-borne radar radome. Background technique [0002] In order to measure and correct the influence of the radome on the performance of the radar antenna, it is an important task in the development process of the seeker to carry out the performance parameter matching of the warhead radome and the radar seeker based on the far-field anechoic chamber (hereinafter referred to as "hood matching"). However, for large-scale missile-borne radome, there are many difficulties in the matching process of the hood, as follows: 1) The missile-borne radome is generally a conical irregular shape, which is heavy and not easy to clamp and fix; 2) There is a high-precision positioning pin guide between the radome and the cabin, and it is easy to be stuck due to the tilt and misalignment of the positioning pin during the assembly process; 3) The radom...

However, for large-scale missile-borne radome, there are many difficulties in the matching process of the hood, as follows: 1) The missile-borne radome is generally a conical irregular shape, which is heavy and not easy to clamp and fix; 2) There is a high-precision positioning pin guide between the radome and the cabin, and it is easy to be stuck due to the tilt and misalignment of the positioning pin during the assembly process; 3) The radome is made of non-metallic wave-transparent material, which is brittle and coated with special coating on the surface. 4) Different functions and different types of missile radome have different sizes and shapes, and the erection platform has poor compatibility with the model; 5) The matching and installation of the radome hood needs to be carried out in a dark room, and the platform operation severely limited space

The existing antenna erection devices are difficult to meet the high-precision and high-reliability erection requirements of large-scale missile radome in the dark room. In addition, the existing technology cannot adapt to different shapes of missile radome, resulting in the need to store and carry a large number of dedicated antenna erection devices , causing an increase in the cost of
