Problems solved by technology

At present, radar dynamic organization methods are mostly aimed at each fusion processing level of multi-radar, and the relationship between different factors is separated, and radar station layout or radar parameters or fusion methods are designed separately. This method is incomplete for the design of multi-radar system resources. , cannot well adapt to the needs of complex environments and targets

Embodiment Construction

[0071] The technical solutions of the present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0072] In one embodiment of the present invention, considering the observation system with N radars that spontaneously send and receive, the multi-radar dynamic adjustment method based on information entropy, such as figure 1 As shown, specifically:

[0073] S1. Receive initial observation data from multiple radars. In this embodiment, the initial observation data may be echo sequences of N radars to the same target, traces of detected targets, or extracted feature vectors.

[0074] S2. Obtain a pre-established observation fusion model, and establish a multi-radar fusion entropy model according to the observed fusion model.

[0075] Specifically, for the fusion processing of target detection, tracking and recognition, a generalized model for multi-radar observation decision-making is established uniformly, as formula...

Abstract

The embodiment of the present invention relates to a multi-radar dynamic adjustment method and device based on information entropy, 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 observation Model, establishing a multi-radar fusion entropy model; S3, optimizing the multi-radar fusion entropy model; S4, adjusting the radar positions of multiple radars, the parameters of each radar, and the fusion method of observation data according to the optimization results. The adjustment method of the present invention can adaptively optimize and adjust radar deployment, radar parameters and fusion methods based on combat tasks at different levels to adapt to dynamic changes in the battlefield environment and targets, thereby achieving the purpose of maximizing the acquisition of target information.

Description

technical field [0001] The invention relates to the technical field of radar system resource management, in particular to an information entropy-based multi-radar dynamic adjustment method and device. Background technique [0002] In practice, the battlefield environment and targets are constantly changing, and it is necessary to organize real-time and dynamic organization of multi-radar system resources, including radar station deployment, radar parameters and fusion methods, to adapt to the ever-changing complex environment and targets according to combat tasks, so as to Maximize the acquisition of target information to achieve the best target detection, tracking or identification, etc. [0003] Depending on the location of the radar relative to the target or the radar parameters are different, the target information obtained will be different, and the accuracy of the result will be different if different fusion methods are used. Moreover, for multi-radar observation deci...
