Description

technical field

[0001] The invention relates to the technical field of electronic countermeasures, in particular to a real-time evaluation method for self-defense electronic countermeasures interference effectiveness. Background technique

[0002] The existing electronic countermeasures jamming effectiveness evaluation methods are all based on the reduction of radar performance, such as: "Construction and Reduction of Active Radar Seeker Jamming Effectiveness Evaluation Index System", Yang Yuanzhi, Wang Xing, Chen You, Zhou Dongqing, Fan Xiangyu, Modern Radar, Issue 8, 2016. The interference effectiveness evaluation system proposed in this paper includes the following factors:

[0003] Interference effect factor: The interference effect factor mainly considers the interference effect from the power level, and is the ratio of the interference signal ratio at the output end of the radar after being interfered with when it is not interfered.

[0004] Effective interception ti...
