Description

technical field [0001] The invention relates to the technical field of signal processing and control, in particular to a frequency scanning beam timing control device and a control method thereof. Background technique [0002] Antenna beam scanning methods are generally divided into mechanical scanning and electronic scanning, and electronic scanning can be further divided into phase scanning and frequency scanning. With the rapid development of computer and integrated circuit technology, the phase scanning system has been widely used in new system radars, such as phased array radar. However, the phased array system based on digital beam forming (DBF) is complex and has a large structure, and the cost of core components (such as TR) is very high. In small and medium-sized radars, although the electronic scanning method with flexible phase control can achieve good detection results and efficient design methods, it is difficult to take into account the requirements of the str...
