Problems solved by technology
Although some scholars have successively proposed a spatio-temporal evidence fusion model, when the time-domain evidence conflicts at adjacent moments, the obtained results will appear unreasonable.
When dealing with time-domain evidence with less conflict, the advantage is not obvious, and the amount of calculation is large

Embodiment Construction
[0052] The present invention is described in detail below in conjunction with accompanying drawing and specific embodiment:
[0053] In order to better understand the content of the present invention, some concepts involved in the present invention are explained below in detail:
[0054] Basic probability assignment function BPA: Let Ω be an identification frame, A is a subset of Ω, if function m:2 Ω →[0,1] satisfies the following two conditions, then it is called a basic probability assignment function (basic probability assignment, BPA for short) on Ω:
[0055]
[0056] for If m(A)>0, then A is called a focal element of Ω, and m(A) is the basic probability quality of A, which reflects the trust degree of evidence on A.
[0057] For the target identification problem, the identification framework of this problem is all types of targets that may be identified. If the target may be identified as three types of fighter (F), transport aircraft (T), and bomber (B), then the...

The invention discloses an information fusion method based on a negotiation strategy in target identification. The method comprises the following steps: (1) determining a time domain information set M; (2) calculating the distance between BPA (m + t-1, mt, mt + 1) at each moment; (3) determining a threshold mu; (4) fusing non-conflict information; and (5) fusing conflict information. The method has the advantages that the fusion method can be selected in a self-adaptive mode according to the conflict degree between time domain evidences, the intelligence and pertinence of the fusion method areimproved, the conflict information processing capacity of the fusion method is enhanced, and the real-time performance and robustness requirements of a target fusion recognition system for uncertaininformation processing are better met.
Description
technical field [0001] The invention belongs to the fields of uncertain information processing and information fusion, and in particular relates to an adaptive fusion method of time-domain evidence based on a negotiation strategy. Background technique [0002] Under the conditions of modern warfare, accurate detection and effective early warning of incoming targets, high-definition reconnaissance and real-time monitoring of the battlefield environment, and precise guidance of one's own weapons all require weapon systems to have all-weather detection, over-the-horizon surveillance, and high-precision identification Ability. However, due to the complexity of the battlefield environment, it is difficult for a single sensor to meet the needs of target recognition. The multi-source information fusion technology based on the multi-sensor platform provides an effective way to solve the difficult problems in the automatic target recognition technology. Multi-source information fus...
