Description
Technical Field
The utility model relates to a protector of phased array radar.
Background
Electromagnetic waves radiated by the radar antenna are radiated to the space through the radome. The antenna housing is made of insulating materials and has small attenuation to electromagnetic waves under normal conditions. However, in rainy days, rainwater forms a water layer on the antenna cover, water is not an insulator, and the electromagnetic waves are greatly attenuated, so that the detection capability of the radar is sharply reduced, and the detection capability is only a fraction or even a fraction of a tenth of that of a fine day.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing an automatic rain-proof cover of gas curtain of phased array radar antenna to solve and prevent or reduce rain at the technical problem of antenna electromagnetic wave transmission direction formation water layer.
In order to realize the purpose of the utility model, the utility model discloses the technical scheme who adopts as follows:
the automatic rain-proof cover of gas curtain of phased array radar antenna includes: the device comprises an upper baffle, two side baffles, an upper fan, a side fan, a rain sensor and a controller; the inner cavity of the upper baffle plate is provided with an upper air duct, and the inner cavities of the two side baffle plates are respectively provided with a side air duct; the upper air duct is in a flat horn mouth shape, the front side gap of the upper air duct is opened at the front edge of the upper baffle plate, the upper fan is positioned at the rear end of the horn mouth of the upper air duct, the inner cavities of the two side baffle plates are also respectively provided with the horn mouth-shaped side air ducts, the front side gap of the upper air duct is opened at the front edge of the side baffle plate, and the side fan is positioned at the rear end of the horn mouth of the side air duct; the upper fan and the anemometer blow airflow forwards from gaps formed by the upper air duct and the side air ducts forwards, and forward speed is provided for forward raindrops, so that the raindrops flying from the front to the antenna move in the direction away from the antenna and do not fall on the antenna; when the radar rains in the sky and rains and raindrops fall on the rain sensor of the upper baffle, the controller connected with the rain sensor senses raining and controls the motors of the upper fan and the side fans to be started to form the rainproof air curtain.
The utility model has the advantages that can ensure phased array radar under the condition of rainy day, overcome the decay of rainwater formation to the electromagnetic wave, still keep normal detection ability.

Detailed Description
The structure of the utility model is shown in the figures 1, 2 and 6. The automatic air curtain rain cover of phased array radar antenna includes: the device comprises an upper baffle, two side baffles, an upper fan, a side fan, a rain sensor and a controller; the inner cavity of the upper baffle plate is provided with an upper air duct, and the inner cavities of the two side baffle plates are respectively provided with a side air duct; the upper air duct is in a flat horn mouth shape, the front side gap of the upper air duct is opened at the front edge of the upper baffle plate, the upper fan is positioned at the rear end of the horn mouth of the upper air duct, the inner cavities of the two side baffle plates are also respectively provided with the horn mouth-shaped side air ducts, the front side gap of the upper air duct is opened at the front edge of the side baffle plates, and the side fan is positioned at the rear end of the horn mouth of the side air duct. The upper baffle plate and the side baffle plate are made of non-metal materials.
See fig. 3 and 4. The upper baffle and the side baffles block rain on the upper surface and the side surfaces and prevent the rain from falling on the radar antenna surface. The upper fan blows airflow forwards from a gap formed by the upper air duct and opens forwards to provide forward speed for the front raindrops, so that the raindrops floating forwards towards the antenna move towards the direction away from the antenna and do not fall on the antenna. The side fan blows airflow forwards from a gap formed by the side air duct forwards to give a forward speed to the side raindrops, so that the raindrops floating from the front to the antenna move in the direction away from the antenna and do not fall on the antenna.
The control principle of the present invention is shown in fig. 5:
in sunny days, the fan does not work. When the radar rains in the sky, and raindrops fall on the rain sensing device of the upper baffle, the controller connected with the rain sensing device senses the raining, and controls the 3 motors to be started to form the rainproof air curtain.
