Description

technical field [0001] The present invention relates to radar knowledge assistance technology, in particular to a dynamic knowledge base design method and device for intelligent radar countermeasures. Background technique [0002] The main task of the electronic warfare system is to recognize the confrontation target and generate the confrontation strategy as soon as possible, so it is extremely important to accumulate the knowledge of the type, function, behavior law of the radiation source target, and provide a priori information for the radar countermeasure system. Since the 21st century, many researchers at home and abroad have started modeling and database construction of radar target characteristics and characteristic data. By collecting a large number of radar target echo data or establishing target simulation electromagnetic models, they have established and expanded target characteristic databases. With the increasingly complex battlefield electromagnetic environmen...
