Problems solved by technology

However, most of the current radar dynamic organization methods are aimed at each fusion processing level of multiple radars, and the relationship between different factors is separated, and the radar station layout, radar parameters or fusion methods are designed separately, so they cannot well adapt to the needs of complex environments and targets.

Embodiment Construction

[0080] The technical solutions of the present invention will be further described in detail below through the accompanying drawings and embodiments.

[0081] In the present invention, from the perspective of adding radar stations, adding a radar is equivalent to increasing the target observation amount, thereby increasing the amount of information to obtain the observation target, which can reduce the uncertainty of the output of the fusion system, and the increased amount of The amount of information is defined as information gain, and it is desirable to increase the amount of information as much as possible. By maximizing the information gain of the multi-radar observation decision, the invention can adaptively optimize the design of multi-radar resources, including radar station positions, parameters and fusion methods, and reduce the degree of uncertainty in acquiring target information.

[0082] In an embodiment of the present invention, considering an observation system ...

Abstract

The embodiment of the present invention relates to a multi-radar dynamic adjustment method and device based on information gain, wherein the method includes: S1, receiving initial observation data of multiple radars; S2, obtaining a pre-established observation fusion model, and performing fusion according to the observations Model, establishing a multi-radar fusion entropy model; S3, calculating the multi-radar information gain according to the multi-radar fusion entropy model; S4, optimizing the multi-radar information gain; S5, adjusting the radar of the multi-radar according to the optimization result Location, parameters of each radar and fusion method of observation data. The method and device of the present invention, by maximizing the information gain, realize the joint self-adaptive optimization design of radar station layout, parameters and fusion methods, so as to obtain target information better.

Description

technical field [0001] The invention relates to the technical field of radar system resource management, in particular to a method and device for dynamic adjustment of multiple radars based on information gain. Background technique [0002] The battlefield environment and combat targets are constantly changing. In order to maximize the acquisition of target information and achieve the best target detection, tracking or identification, it is necessary to monitor multiple radar system resources according to combat tasks, including radar station deployment, radar parameters and fusion methods. etc., perform real-time dynamic organization to adapt to changing complex environments and goals. [0003] Different radar stations, radar parameters and fusion processing methods will result in different target information and its accuracy. And, for multi-radar observation decisions, the effects of these factors are coupled. However, most of the current radar dynamic organization metho...
