Problems solved by technology

[0003] (1) Since there are too many aspects of radar threat assessment, it is more often scored according to experienced experts, and subjective factors occupy a large part
[0004] (2) Most of the existing radar threat assessments only perform simple linear superposition, resulting in many methods that cannot accurately measure the radar threat, or cannot measure it

Embodiment Construction

[0030] The following examples describe the present invention in more detail.

[0031] The invention provides a method for realizing maximum radar interference by predicting the radar working mode. Since the traditional method is aimed at one-to-one or many-to-many radar jamming methods, it does not take into account that the working mode of the radar will change with the different jamming methods. When the working mode of the radar changes, the jammer does not It can immediately identify the working mode of the radar and change its interference mode, resulting in the inability to maximize the interference of the jammer. Therefore, the present invention proposes a method for predicting the radar working mode, and enables the change of the jamming mode of the jammer to follow the change of the radar working mode, so as to realize the maximization of the jamming benefit.

[0032] The invention includes the following modules: a radar signal acquisition module, a radar signal proc...

Abstract

The invention provides a cognitive interference method based on Markov process decision. Firstly an interference machine detects the main changes of the radar signals so as to identify the working mode of the radar and establish the Markov chain of working mode state transition, then the transition probability of the established radar working mode transition Markov chain is calculated by using theproper algorithm, and finally the radar working mode transition probability is converted into the matrix form to predict the next working mode of the radar so that the interference machine is enabledto interfere the radar signals to the greatest extent. The interference machine selects the proper interference mode for the working mode of the radar so that the benefit of interference is maximized. The radar interference threat is not assessed so as to avoid incomprehensiveness and inaccuracy of assessment. The next working mode of the radar can be further predicted according to the obtained radar working mode state transition matrix so that the interference machine is enabled to take the active position.

Description

technical field [0001] The invention relates to an information fusion and control decision-making method, in particular to an optimal decision-making method for realizing radar interference based on Markov state transition. Background technique [0002] Radar jamming decision-making has become one of the hot areas that researchers pay attention to. Many scholars have proposed various methods for radar jamming decision-making, which are mainly divided into two aspects: one is to allocate one jammer to one radar, and the other is to allocate multiple jammers to multiple radars. The premise of their realization is that it is necessary to make an assessment of the radar threat, and this kind of assessment has a wide range, for example, it needs to be assessed from the aspects of space domain, polarization domain, energy domain, time domain and frequency domain. One-sidedness, so it is not possible to accurately assess the threat of each radar. In many occasions, the evaluation...
