在这项研究中,针对相控阵雷达(PAR)网络中的多目标跟踪(MTT),提出了一种最佳的资源分配(ORA)策略。 PAR网络的主要目标是在必须满足所需MTT精度的情况下,将系统的资源消耗降至最低。 在此基础上,我们开发了一种新颖的资源分配模型,并证明了该模型是凸的和可分离的。 通过使用CVX工具箱并行解决子问题,可以轻松获得最佳解决方案。 仿真结果表明,与统一分配资源方案相比,ORA策略需要较少的资源来实现预定的MTT性能。

This lecture series gives comprehensive overview of the broad field of advanced radar systems, signal and data processing. The series starts with a lecture by U. Nickel in which the basic and fundamental of signal processing for phased array radar and their problems with grating lobes, ambiguities, and angle estimation for instance. The lecture “Advanced target tracking techniques” by W. Koch gives a short introduction to the principle of target tracking and several approaches are discussed for sequential track extraction and for phased-array radars. In the third lecture P. Berens gives an introduction to the synthetic aperture radar (SAR). T. Johnsen provides an overview of bi- and multistatic radar and their associated problems like synchronization, timing, and signal processing. The second lecture of U. Nickel focuses on the problem of adaptive array signal processing and provides the fundamental understanding for the next two lectures. The focus of these lectures, presented by W. Bürger, is on space-time adaptive processing. In his second lecture P. Berens continues with the topic of the synthetic aperture radar and expands the presented techniques to wideband SAR and multichannel SAR/MTI systems. W. Koch’s second paper focuses on sensor data and information fusion, which is essential to extract key-information for the final judgement using several sensors. In summery, this Lecture Series presents a unique overview of the state of the art of advanced radar and the associated signal and data processing research. It offers a variety of material for all those being involved in this scientific area, e.g. students, university teachers, researchers, industrial system designers, and military users.

针对二维混合多输入多输出(MIMO)相控阵雷达发射子阵分割带来的自由度损失进而影响雷达系统参数估计性能的问题,提出一种基于十字阵的二维稀疏混合MIMO相控阵雷达收发阵列设计方法.首先,结合稀疏阵列-共轭嵌套阵对混合MIMO相控阵雷达的收发端进行稀疏设计;其次,对混合MIMO相控阵雷达产生的合阵进行做差处理,得到阵元位置差的差异阵列;最后,通过空间平滑处理进行波达方向估计.仿真实验表明,相较于传统的二维混合MIMO相控阵雷达,所提出方法仅利用两个互相垂直的一维线阵便可形成阵列的二维平面扩展,同时,在不增加阵元个数的前提下可有效扩展雷达阵列虚拟阵元数目,提高阵列的自由度以及波达方向估计性能.
