Background
One of the important performances of the radome is to ensure the wave-transmitting performance and the reliability of the communication between the internal antenna and the external radar. With the progress of research, some antennas require direct assembly into the structural components of the radome and have considerable accuracy requirements. This puts high demands on the method of assembly of the antenna to the radome.
The most traditional method is to directly manufacture a mounting hole on the structural part of the radome, and sequentially install and fix the antenna rods in the mounting hole. The method cannot ensure the installation precision and has great adverse effect on the performance of the antenna in the later period.
