Embodiment Construction

[0019] The present invention will be further described below in conjunction with the accompanying drawings and embodiments, and the present invention includes but not limited to the following embodiments.

[0020] The invention provides an application of a folded and leveled structure of a Ku-band high-precision slot array antenna, which is used to ensure high pointing accuracy of a radar to obtain a space target position.

[0021] The auxiliary antenna 2 is installed on the right side of the main antenna 1. The width of the main antenna 1 is 2700mm, and the width of the auxiliary antenna 2 is 450mm. The overall requirement is that the width direction of the upper surface of the main antenna in the transportation state is less than 2850mm. In order to meet the vehicle transportation conditions of the radar, the auxiliary antenna 2 must be placed in the It can be folded in the transportation state and can be unfolded quickly when working. Antenna working and transport status (s...

Abstract

The invention provides a folding and leveling structure of a Ku-waveband high-precision gap array antenna. One side of an auxiliary antenna is hinged to one side of a main antenna through a support lug, and when the auxiliary antenna is unfolded, a radiating surface is flush with a radiating surface of the main antenna; and a length-adjustable support rod is hinged to the other side of the auxiliary antenna through an upper support lug, the other end of the support rod is matched with a connecting ball head at one side of the main antenna through a connecting conical head, the connecting conical head is externally coaxially equipped with a sliding sleeve, and the sliding sleeve is in threaded connection with the connecting ball head. The folding and leveling structure of the Ku-waveband high-precision gap array antenna can ensure that stability, flatness and parallelism meet requirements after the auxiliary antenna are unfolded.

Description

technical field [0001] The invention belongs to the field of antenna mechanical engineering measurement and relates to a leveling and folding device for a phased array antenna. Background technique [0002] The waveguide slot array antenna is mainly used as the electronic scanning antenna of the phase-frequency scanning radar. Compared with the complete phase-scanning antenna, it is widely used for ground and low-altitude targets because of its small number of phase shifters, low antenna cost, simple structure, and light weight. in the reconnaissance radar. The so-called phase-frequency sweep antenna refers to an array antenna composed of multiple rows of parallel linear slot waveguides, and a phase shifter is connected in series at the input end of the waveguide to change the phase shift amount of the phase shifter, so that the phase between each slot waveguide changes, and the wave The direction of the lobe changes accordingly, which realizes the phase scanning in the wid...
