Problems solved by technology

Although these technologies can suppress some electromagnetic interference, they have their own limitations, and require a large investment in technology and funds. At the same time, it is necessary to know in advance the interference that the radar's location may receive, and these are in the radar development and design process. hard to know

Embodiment Construction

[0017] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0018] The first example is figure 1 , 2 , 3, 4, and 6, including the base 3 and the pot-shaped radar antenna 1 and the feed source 2 installed on the base, the sheet-shaped metal shielding plate 4 is symmetrically arranged on both sides of the pot-shaped radar antenna aperture edge, The plate surface of the metal shielding plate is perpendicular to the aperture surface of the pot-shaped radar antenna, the center point of the metal shielding plate 4 is flush with the midpoint of the aperture edge of the pot-shaped radar antenna 1, and the shortest distance from the aperture edge of the radar antenna is R 0 = 1 m. The metal shielding plate is supported by a non-metal support frame 5 installed on the base. The metal shielding plate 4 and the supporting frame 5 can rotate together with the base 3 and the radar 1 . The shape of the metal baffle 4 is calc...

Abstract

This invention relates to one shield device to prevent antenna electron-magnetic interference in capacity field, which comprises base socket and kettle radar antenna feedback source on the socket andis characterized by the following: both sides of kettle radar antenna fringe; metal shield block surface is vertical to the kettle radar antenna radium; metal shield board is fixed on the metal supportive rack on the socket. These invention sets the metal shield block beside the radar antenna to form radar side prevent device.

Description

technical field [0001] The invention relates to a shielding device for suppressing radar antenna electromagnetic interference, which belongs to the field of electromagnetic compatibility. Since the radar is a transceiver device, the shielding device can be used not only to block the interference of the harmful electromagnetic radiation from the side lobe of the radar antenna to other equipment, but also to suppress the interference of the electromagnetic radiation of other radars and electronic equipment to the radar itself. Background technique [0002] Radar antenna anti-jamming technology has always been a hot research topic at home and abroad, and many related control technologies have emerged, including filter technology (harmonic suppression filter, adjustable band-pass filter and band-pass filter, etc.), this technology Larger economic investment is required; concealment technology (including sector concealment, pulse concealer, side lobe concealment, etc.), this tech...
