Abstract:

With the continuous development of multifunctional radar (MFR) and cognitive electronic warfare technology, traditional jamming decision-making systems are increasingly difficult to meet the needs of modern warfare. Aiming at this, a cognitive jamming decision-making system against MFR is constructed. Firstly, the hierarchical structure of MFR signal is constructed. On this basis, combined with cognitive characteristics, a cognitive jamming decision-making system is proposed, which makes the decision-making system of MFR jamming have certain cognitive ability. Secondly, the key technologies in the system are analyzed, including the construction and updating of jamming library and case library, the analysis of jamming effectiveness, and the jamming strategy based on reinforcement learning. It has important theoretical and pratical significance for the development of cognitive electronic warfare.

Key words: jamming decision-making system, multifunctional radar (MFR), signal hierarchy structure, cognitive electronic warfare, jamming effectiveness analysis, reinforcement learning
