Anti-interference shielding device for shipborne microwave omnidirectional antenna

Abstract

The invention discloses an anti-interference shielding device for a shipborne microwave omnidirectional antenna. Theanti-interference shielding device comprises a base, wherein the middle part of the top surface of the base is connected with the bottom end of a microwave omnidirectional antenna; a guide rail is arranged around the outer edge of the base; an annular groove is formed in the upper surface of the base; a first driving module is arranged in the base; the shielding reflecting cover comprises a bracket and a cover body; the bracket consists of a first bracket, a second bracket and a second driving module; an intelligent adjusting system comprises a distance module, a first signal detection module, a second signal detection module, a third signal detection module and a main controller; and the main controller controls actions of the first driving module and the second driving module according to detection data obtained by the distance module, the first signal detection module, the second signal detection module and the third signal detection module. By monitoring radiation signals of the antenna in all directions in real time, interference signals can be shielded in the direction with weak radiation signals or in the direction with strong interference, reflection signals and emission signals are subjected to phase superposition, gain is generated, and then the radiation capacity of the antenna is improved.

Description

technical field [0001] The invention relates to the technical field of microwave antennas, in particular to an anti-interference shielding device for a ship-borne microwave omnidirectional antenna. Background technique [0002] An antenna is a transformer that transforms a guided wave propagating on a transmission line into an electromagnetic wave propagating in an unbounded medium, or vice versa. A component used in radio equipment to transmit or receive electromagnetic waves. Engineering systems such as radio communication, broadcasting, television, radar, navigation, electronic countermeasures, remote sensing, and radio astronomy, which use electromagnetic waves to transmit information, rely on antennas to work. In addition, in terms of transmitting energy with electromagnetic waves, non-signal energy radiation also requires antennas. [0003] Most of the existing antennas are omnidirectional radiation antennas. When two omnidirectional radiation antennas are close to e...

AI Technical Summary

Problems solved by technology

[0003] Most of the existing antennas are omnidirectional radiation antennas. When two omnidirectional radiation antennas are close to each other, the mutual interference will seriously affect the user access rate and data transmission rate. At the same time, when the interference is serious in a certain direction or When the signal needs to be oriented in a certain direction to enhance the signal, the omnidirectional antenna cannot be adjusted, and even when the directional antenna is used, the direction of the directional antenna needs to be manually adjusted to meet the user's needs
