TECHNICAL FIELD
[0001] The present application relates to the technical field of electronic countermeasures, in particular to a portable multifunctional AI-enabled electronic countermeasure system. BACKGROUND
[0002] Currently, commercial and consumer drones are increasingly used in various complex application scenarios. Such drones have the characteristics of low cost and easy operation, but in actual application, they show significant effects and potential interference risks. The introduction of FPV (first-person view) drones further amplifies this threat, as their high mobility, flexible flight paths, and real-time manual loop control mode make them highly adaptable aerial platforms in certain special application environments.
[0003] The widespread use and demonstrated technical potential of the above-mentioned drones have prompted increased investment in small and micro drone systems by various parties, as well as in-depth thinking about effective monitoring and control technologies for such drones.
[0004] In addition to physical interception methods, the main non-physical denial means include electronic countermeasure technology, which is an important soft-killing method. Traditional large and medium-sized electronic countermeasure systems are usually designed for large radars and other large radiation sources, mainly serving macro-strategic and campaign-level tasks. Consumer drones, on the other hand, are low-altitude, slow, and small targets with limited flight distances and variable behavior patterns. Therefore, traditional electronic countermeasure systems not only have technical mismatches when dealing with such targets, but also lack effectiveness in terms of economy and applicability. In addition, large electronic countermeasure systems are bulky and easily deployed, making it difficult to achieve rapid and concealed deployment and agile response, and unable to meet the high-efficiency disposal needs of sudden low, slow, and small drone targets.
