Problems solved by technology

The second is that only static analysis can be performed, and it is impossible to evaluate the effectiveness of electronic countermeasures in real time based on the battlefield situation and feedback. For example, once the effective interception time is determined, the interception time of this type of seeker is determined.
The third is that the indicators focus on technology, which is not directly helpful to combat auxiliary decision-making

Embodiment 1

[0027] A method for real-time evaluation of self-defense electronic countermeasures interference effectiveness provided by this embodiment includes:

[0028] Step 1: Establish an interference effectiveness evaluation algorithm by obtaining the probability of missile strikes by different battlefield situation downloaders; at least one of digital simulation, semi-physical simulation, test, training and exercise can be used to obtain different battlefield situation downloaders. probability of hitting.

[0029] In step 2, the current battlefield situation data is used as input, and the current survival probability of the carrier aircraft is calculated in real time through the established interference effectiveness evaluation algorithm.

[0030] The present invention is described below through the scenario of a carrier aircraft against a surface-to-air missile system:

[0031] The aircraft equipment (our equipment data) includes:

[0032] Radar alarm, its working status includes:...

Abstract

The invention discloses a real-time evaluation method for self-defense electronic anti-jamming effectiveness, which includes: step 1, establishing a jamming effectiveness evaluation algorithm by obtaining the probability that a downloader in different battlefield situations is attacked by a missile; step 2, taking the current battlefield situation data as input, The current survival probability of the carrier aircraft is calculated in real time through the established interference effectiveness evaluation algorithm. The invention realizes the real-time evaluation of the combat effectiveness of the electronic countermeasure by establishing a unified electronic countermeasure interference effectiveness evaluation algorithm aimed at combat applications, thereby assisting operators to complete tactical decision-making.

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...
