Description

technical field [0001] The invention relates to a control device, in particular to a phased array radar antenna beam control device. Background technique [0002] With the wide application of new technologies, more challenges have been brought to the wave control system of phased array radar antennas. The characteristics of small unit spacing and complex structure have put forward high requirements for the wave control system: fast calculation speed, equipment It has changed from simple beam pointing control to comprehensive electrical control of radar antenna system, and the selection of circuit modules tends to be highly integrated and ASIC. [0003] At present, the control scheme used in the phased array radar antenna wave control system is mainly composed of PC-104 framework computer module + FPGA chip in the field of industrial control. In a high-vibration environment, the contact may be poor, which cannot meet the high reliability requirements of the system. Content...
