However, improper allocation of resources severely restricts the improvement of EE and substantially elevates communication costs of SWIPT. To address these issues, this study proposes a joint resource allocation algorithm for optimizing user scheduling, power allocation, and power splitting based on distributed multi-agent double deep Q-network and double multi-agent deep deterministic policy gradient (MADDQN-DMADDPG) network. Specifically, a double deep Q-network (DDQN) is used to optimize user scheduling by decoupling the action selection from action evaluation, which resolves the Q-value overestimation and mitigates multi-user interference. Then, to improve the training stability, a deep deterministic policy gradient (DDPG) is utilized to optimize the power allocation and power splitting by leveraging its ability to handle continuous action spaces. Moreover, we introduce the distributed multi-agent learning to bolster the learning capabilities of DDQN and DDPG, ensuring accuracy and efficiency of resource allocation.

Radomes of this type are typically non-developable surfaces, while current academic research lacks dedicated modeling methodologies specifically for aircraft nose-conFigured quasi-conical FSS radomes. This paper focuses on addressing this challenge by proposing an efficient modeling method for constructing complex FSS arrays on new-generation fighter aircraft nose-conFigured quasi-conical radomes. The method employs a virtual developable conical mold to achieve minimal-distortion flattening of quasi-conical non-developable surfaces, establishing a complete mapping relationship between the minimally distorted flat-unfold plane and the original non-developable radome surface. This mapping enables linear transfer of pre-designed FSS arrays from the minimal-distortion flat-unfold plane to the non-developable radome surface, thereby generating a 3D digital model of the nose-conFigured quasi-conical FSS radome. Compared to traditional methods, this approach establishes a minimum-distortion complete mapping without compromising modeling accuracy while requiring only approximately 30% of the computational time of conventional techniques. This significantly enhances computational efficiency for modeling complex FSS arrays on quasi-conical undevelopable radome surfaces. The process of the modeling is presented in this paper in detail, and the effectiveness of the proposed method is validated by constructing FSS arrays on radomes of two typical types of fighter aircraft.</div></div>","PeriodicalId":50844,"journal":{"name":"Aeu-International Journal of Electronics and Communications","volume":"201 ","pages":"Article 155948"},"PeriodicalIF":3.0,"publicationDate":"2025-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144704572","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
