Embodiment Construction

[0056] The specific implementation manners of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0057] This embodiment provides a method for judging that the radiation source radar belongs to the target platform, refer to figure 1 , the discriminant method includes the following steps:

[0058] S1. Obtain characteristic parameter values ​​of multiple intercepted radiation sources and calculate the membership degree of each characteristic parameter of each intercepted radiation source belonging to each radar in the database.

[0059] Through reconnaissance and interception of multiple unknown radar emitter target signals, according to their pulse arrival time, it can be concluded that their positions are similar, and by comparing their incoming wave azimuth angles, it is preliminarily determined that these radars belong to the same combat platform. Their characteristic parameters are as follows: carrier frequency RF, puls...

Abstract

The invention provides a method for judging whether a radiation source radar belongs to a target platform. The method comprises the following steps: calculating the membership degree of each characteristic parameter of each radar in a database to which each intercepted radiation source belongs; carrying out normalization processing; calculating the entropy weight of each intercepted radiation source belonging to each radar in the database; selecting the maximum entropy weight from the entropy weights of the radars belonging to the database of each interception radiation source as the credibility of the corresponding radar belonging to the database of the corresponding interception radiation source, and constructing a credibility matrix of the interception radiation sources and the radars; obtaining a target platform associated with all radars in the database in which the interception radiation source belongs and corresponding confidence from the database; constructing a confidence coefficient matrix of the radar and the target platform; multiplying the credibility matrix by the confidence coefficient matrix; and selecting the platform corresponding to the maximum multiplication result value as a target platform to which the corresponding radar belongs in the database to which each interception radiation source belongs. According to the invention, the discrimination accuracy and discrimination efficiency of the radiation source platform target are greatly improved.

Description

technical field [0001] The invention belongs to the technical field of signal processing, and in particular relates to a method for judging that a radiation source radar belongs to a target platform. Background technique [0002] In military operations, the use of radar radiation source signal parameter information to identify the platform target to which it belongs is a key link in radar countermeasure intelligence processing. Facing the increasingly complex electromagnetic environment and the rapid development of radar technology, the original single radar radiation It is often difficult to achieve high-accuracy platform discrimination and meet the needs of operational decision-making for electronic intelligence by using source characteristic parameters to identify the platform target it belongs to. To study the potential association rules and knowledge between the radar radiation source and the target platform, and then realize the high-accuracy model discrimination of th...
