Abstract

In this paper, we address the target localization problem based on hybrid range and angle measurements with unknown transmit power in both noncooperative and cooperative scenarios, respectively. By analyzing the approximate expressions of the noise terms in the measurement models, an original nonconvex localization problem is formulated according to the least square criterion. This problem is transformed into a mixed semi-definite programing/second-order cone programing by using convex relaxation techniques. Computer simulation results verify that the proposed algorithm can effectively solve the localization problem with good performance in the unknown transmit power case.

无线传感器网络中基于 RSS-AOA 的混合定位与未知发射功率

在本文中，我们分别讨论了在非合作和合作情况下，基于未知发射功率的混合测距和角度测量的目标定位问题。通过分析测量模型中噪声项的近似表达式，我们根据最小平方准则提出了一个原始的非凸定位问题。利用凸松弛技术将该问题转化为混合半有限编程/二阶锥编程。计算机仿真结果验证了所提出的算法能有效解决未知发射功率情况下的定位问题，且性能良好。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
