A multi-target positioning method and device for mitigating non-line-of-sight effects, medium

Abstract

The present application relates to a kind of multi-target positioning method, equipment, medium for mitigating non-line-of-sight effect, the method comprises the following steps: obtaining RSSD data, and conversion is into preset format;The RSSD data converted into preset format is input into pre-trained multi-target positioning model for mitigating non-line-of-sight effect, obtains multi-target positioning information, completes multi-target positioning, wherein the acquisition of pre-trained multi-target positioning model for mitigating non-line-of-sight effect includes: constructing RSSD multi-target positioning model under non-convex NLOS, generates experimental data set, each sample includes multiple target node real position information and corresponding RSSD data;Multi-target positioning model is trained based on experimental data set until loss function value reaches preset convergence condition.Compared with prior art, the present application mitigates the influence of non-line-of-sight environment, while being easy to implement, and multiple targets can be estimated in parallel.
