Description
Technical Field
The utility model relates to a radar antenna technical field, concrete field is a high strength honeycomb intermediate layer antenna house.
Background
The radar antenna feeder system is an important component of a radar system and is mainly used for transmitting or receiving electromagnetic wave signals. In the process of the electromagnetic wave propagating in the space, the intensity of the electromagnetic wave is inversely proportional to the transmission distance, and in order to increase the action distance, the power of the transmitted electromagnetic wave signal needs to be increased. When high-power electromagnetic waves are transmitted in the radar antenna feeder system, air breakdown is caused due to overhigh electric field intensity, and therefore a sparking phenomenon is generated in the antenna feeder system, namely, physical damage of antenna feeder devices is caused, and harmonic components of the electromagnetic waves are generated to influence the signal-to-noise ratio of radar signals.
Because the breakdown field intensity is in direct proportion to the gas pressure of the antenna feeder system and in inverse proportion to the water content of the gas, the measures for solving the ignition of the high-power radar antenna feeder system are mainly two: charging a high pressure gas and drying the charged gas.
This puts higher demands on the sealing of the antenna system and the design of the radome.
Traditional radome mainly seals the antenna face, avoids steam and dust to enter into the antenna face, causes antenna face corrosion or pollution, consequently, traditional radome has the poor problem of rigidity. The high-power antenna system requires that air in the antenna feeder system is firstly pumped out and then dried high-pressure air is filled in, and the antenna housing with poor rigidity cannot meet the requirement on strength.
