Problems solved by technology

The heat dissipation efficiency of forced air cooling is lower than that of liquid cooling. Although the overall cost of the radar and the maintenance cost in the later period are reduced, because the air cooling method needs to install more fans on the front, the front work will generate a lot of noise. , and the failure rate of the fan is high, and the environmental adaptability is poor, which will reduce the reliability of the radar

Abstract

The invention discloses an extensible open type active phased-array antenna array plane. The invention relates to the technical field of active phased-array antenna array planes. The extensible open type active phased-array antenna array plane specifically comprises a box body, the top of the box body is fixedly connected with sub-array planes, the surfaces of the sub-array planes are provided with conductive pressing strips, the side surface of the box body is provided with an air inlet, the top of the box body is provided with air outlets at positions corresponding to the sub-array planes, and the box body is internally provided with a primary comprehensive network and a primary inflation network. An array plane structure adopts a building block type design method, the array plane is divided into a plurality of identical sub-array planes through reasonable structural layout and module division, the sub-array planes can be expanded transversely and longitudinally to form a large antenna array plane, and the expansion number of the sub-array planes can be determined according to actual use requirements. The conductive pressing strips are arranged among the sub-array planes so as toensure the electrical continuity of the reflection plane of the whole array plane radiation unit. Each sub-array plane can be debugged, transported and operated independently, and the problems that alarge radar antenna array plane is difficult to transport and install and long in debugging period are solved.

Description

technical field [0001] The invention relates to an active phased array antenna front, in particular to an expandable open active phased array antenna front. Background technique [0002] Active phased array radar has the advantages of flexible and controllable beams and high reliability, and its application in ground fixed radars has become increasingly widespread. , integrated design level, etc. determine the performance and cost of the entire radar system. [0003] At present, in the face of many task requirements such as fast real-time tracking of high-speed moving targets and longer detection distances, radars with larger apertures and higher reliability are required. Existing active phased array antennas are generally composed of several antenna modules with the same structure and function. The structure is complex and there are many devices. If the traditional phased array design method is adopted, the antenna array will have a large size and heavy weight. , The rada...
