Background
The high-precision array antenna radar plays an extremely important role in modern electronic information equipment, and is an important component of a large national weight device such as a detection system and the latest weapon equipment. The array antenna radar consists of hundreds to tens of thousands of array elements (antenna units), the array elements are core parts of the radar, and the array antenna radar has the advantages of flexible beam direction, large target capacity, strong adaptability to complex target environments, good anti-interference performance and the like, and the performance is far superior to that of the traditional radar. At present, experimental research on array antennas is carried out in all strong countries in the world, and the array antennas are used for military equipment such as airborne radars, early warning detection systems, destroyers and the like. The high-precision array antenna radar which is experimentally researched in China is also applied to military equipment.
The traditional radar has a transmission line for receiving signals, and the high-precision array antenna radar also has a special signal transmission line, namely a radio frequency coaxial cable. The radio frequency coaxial cable is only 1.18mm in diameter and semi-rigid, has a three-layer structure of outer conductor stainless steel, middle layer polytetrafluoroethylene and inner conductor copper, and is required to be formed into a three-dimensional bent shape in order to adapt to the structure of the array antenna. At present, the manual extrusion of the cable into a die for forming is adopted in China, the forming precision is difficult to ensure and easy to deform, the inner conductor is easy to scratch, the overall process efficiency is extremely low, and the requirement of the array antenna radar is difficult to adapt.
