Radar communication antenna capable of precisely adjusting signal receiving height and azimuth

Abstract

The invention relates to a radar communication antenna capable of accurately adjusting signal receiving height and orientation, comprising a base, a base frame is welded on the base, and a base cover is welded on the top of the base frame; the base frame is provided with a guide groove in a spiral structure, the base frame The outer wall is equipped with a support sheet in a spiral structure, and a guide chute in a spiral structure is arranged on the support sheet; a ring-shaped guide mechanism is installed at the lower end of the base cover, and a rotating gear is installed at the lower end of the ring-shaped guide mechanism. The left and right sides of the rotating gear Both ends are meshed with a driving mechanism; a sliding mechanism is installed in the guide chute, and an antenna mechanism is installed on the sliding mechanism; a winding mechanism is installed on the lower surface of the rotating gear, and the driving mechanism, rotating gear, ring guide mechanism, The mechanism, the sliding mechanism and the antenna mechanism cooperate to move to complete the spiral lifting and guiding process of the antenna mechanism. The invention can realize the functions of stable automatic spiral lifting signal height of radar antenna and precise adjustment of signal receiving azimuth.

Description

technical field [0001] The invention relates to the technical field of communication antennas, in particular to a radar communication antenna capable of precisely adjusting the height and orientation of signal receiving. Background technique [0002] The antenna is a converter whose main function is to transform the guided wave propagating on the transmission line into electromagnetic waves propagating in the unbounded medium. Antennas are used in radio equipment as components for transmitting or receiving electromagnetic waves, and are widely used in radio communications, broadcasting, TV, radar, navigation, electronic countermeasures, remote sensing, radio astronomy and other engineering systems. Antennas can be divided into communication antennas, broadcast antennas, TV antennas, and radar antennas according to their uses, among which radar antennas are widely used. [0003] In order for the radar antenna to receive the strongest antenna signal, it must be as consistent ...

AI Technical Summary

Problems solved by technology

[0004] In order to solve the above problems, the present invention provides a radar communication antenna that can accurately adjust the signal receiving height and azimuth, which can solve the problems of manual adjustment of the radar antenna signal receiving height, such as difficulty in grasping the adjustment height range, poor stability of manual adjustment height, and radar antenna There is an error between the azimuth angle of the radar antenna and the azimuth angle of the radar transmitting signal, there is no adjustment to the appropriate signal receiving azimuth, and the signal receiving effect is poor. It can realize the stable automatic spiral lifting signal height of the radar antenna and the precise adjustment of the signal receiving azimuth function. The radar antenna can be used Accurately adjust to the required signal receiving height and signal receiving azimuth, the spiral lifting adjustment process has good stability, the signal azimuth adjustment has good stability, and the signal receiving effect is good, providing a new way of high-efficiency radar antenna signal adjustment
