This paper studies the problem of tracking a ballistic object in
the reentry phase by processing radar measurements. A suitable
(highly nonlinear) model of target motion is developed and the
theoretical Cramer—Rao lower bounds (CRLB) of estimation
error are derived. The estimati ...

传感器网络中基于到达时间差有效的凸松弛方法的稳健定位
We consider the problem of target localization by a
network of passive sensors. When an unknown target emits an
acoustic or a radio signal, its position can be localized with multiple
sensors using the time difference of arrival (TDOA) information.
In this paper, we ...

基于正交训练序列的MIMO系统联合最大似然时频同步和信道估计
摘 要：该文推导了多输入多输出(MIMO)系统中的符号定时、频偏和信道参数的联合最大似然(ML)估计。针对联合ML 估计没有闭合的表达式、数值计算复杂度高的问题，该文提出了一种基于重复结构的正交训练序列的简化估计算法。该估计算法形式简单、复杂度低，且仍为最大似然估计。最后仿真分析了最大似然参数 ...

基于流形分离技术的稀疏均匀圆阵快速DOA估计方法
摘 要：该文针对阵元数有限以及阵元稀疏的均匀圆阵，提出基于流形分离技术(Manifold Separation Technique，MST)的快速波达方向估计算法，PM-Root-MUSIC 方法。该方法避免了均匀圆阵中基于相位模式激励原理的波束空间变换所带来的映射误差，同时利用传播因子(PM)和根MUSIC 算法，避免了传统算法中的特 ...
