该研究通过加权最小二乘(WLS)粗估计与代数误差缩减(ER)两步优化，显著提升高度方向定位精度，理论证明其渐近达到克拉美罗下界(CRLB)，为雷达系统配置优化提供新思路。 在雷达探测领域，高空目标的精确三维定位始终是技术难点。传统基于双基地距离(BR ...

结果表明其降低计算复杂度且定位性能优异，还推导了 CRLB，为 CD 源定位提供新方案。 在无线通信与定位技术领域，复杂环境中的信号散射现象一直是制约定位精度的关键瓶颈。传统基于点源模型的直接定位（DPD）方法在面对城市建筑群、无人机群等多径密集 ...

An emergency rule of Rhode Island CRLB went into effect this morning “in response to the State of Emergency issued by the Governor.” The rule seeks “limit in-person contact while continuing ...

Wednesday afternoon, Mark Young Jr. asked the Rhode Island Contractors’ Registration and Licensing Board (CRLB) for a conditional reinstatement of his registration. Attorney John Harwood vouched ...
