Abstract

The invention provides a common-type radar antenna cover and a winding forming method and relates to the field of radar antennas. The radar antenna cover comprises an isolation medium, a glass fiberglass cloth tape, a waterproof film and a glass fiber winding tow, wherein an antenna array is coated with the isolation medium, the glass fiberglass cloth tape, the waterproof film and the glass fiberwinding tow from inside to outside in sequence. The radar antenna cover is characterized in that the effect of integrating the radar antenna cover with the antenna array in a common type is achieved.By means of the structure, not only is the structural strength of the thin-walled antenna cover ensured but also the rigidity and wind resistance of the antenna array are enhanced, and the electricalperformance of the antenna array can be ensured.

Description

technical field [0001] The invention relates to the field of radar antennas, in particular to a common type radar radome and a winding forming method. Background technique [0002] The radar antenna is in the shape of a long cylinder, the antenna is 20 meters above the ground, and it can withstand the wind speed of 45 m / s without being damaged. In addition, due to the electrical performance requirements of the antenna for the radome, the radome is required to be thin-walled (thickness not greater than 1.2mm) and cannot be attached to the surface of the antenna. The high wind resistance erected at high altitude requires the strength of the antenna, and the electrical performance requirements of the antenna for the high wave transmittance of the radome. [0003] In view of the special requirements of the radar for the radome, an integrated structure of antenna-isolation medium-cover is designed, so that the radome can pass through the transition of the isolation medium to mak...
