项目摘要

Recently, researchers have considered the application of multiple-input multiple-output (MIMO) techniques developed for wireless communication systems to the radar scenario. In MIMO systems, multiple antennas are employed at both transmitter and receiver to increase the data rate and reduce the effect of rapid changes in the radio channel with time. In the context of radar systems, mono-static or bi-static MIMO radars could be used to reduce the impact of scintillation effects, by illuminating the target from multiple transmit antennas but with the same total transmitter power budget. MIMO radars could also reduce the search time to find targets by transmitting multiple waveforms simultaneously, which allows more efficient searching of transmit angle. Further, MIMO processing increases the effective degrees of freedom in the radar system and may thus increase tolerance to echoes from the ground in radar systems and from the sea floor in sonar systems as well as deliberate man/made sources of interference. Since the emergence of MIMO radar concept international activity has focused both on the underlying theory, confirming the significant potential gains in detection and resolution performance that might be achieved, and on developing signal processing algorithms to facilitate these gains. What we propose here is to exploit the work we have already done in (i) methodologies for calculating detection performance in realistic MIMO radar or sonar scenarios; (ii) adaptive detection techniques for radar array-based signal processing that do not require secondary training data. We address the open research questions whose solution will facilitate industrial exploitation of the MIMO radar concept. In particular these are: (i) the design of correlation controlled constant amplitude MIMO waveforms; (ii) the development of adaptive receiver algorithms capable of working in environments of unknown clutter statistics and within the constraints of limited bandwidth communication channels between individual TR/RX pairs. A further novel aspect of the work will be the application of and assessment of MIMO concepts in sonar environments. What we propose is a rigorous generic approach to the understanding and application of MIMO detection. The results will be tested and validated in radar and sonar applications using detailed computer modelling techniques for both target and the medium. In the sonar case they will also be tested with measured data.

最近，研究人员已经考虑将为无线通信系统开发的多输入多输出（MIMO）技术应用于雷达场景。在MIMO系统中，在发射机和接收机处均采用多个天线以增加数据速率并减小无线电信道随时间的快速变化的影响。在雷达系统的背景下，单基地或双基地MIMO雷达可以用于通过从多个发射天线照射目标但具有相同的总发射机功率预算来减少闪烁效应的影响。MIMO雷达还可以通过同时发射多个波形来减少搜索时间以找到目标，这允许更有效地搜索发射角度。此外，MIMO处理增加了雷达系统中的有效自由度，并且因此可以增加对雷达系统中来自地面的回波和声纳系统中来自海底的回波以及故意的人为干扰源的容忍度。自从MIMO雷达概念出现以来，国际活动既集中在基本理论上，确认可能实现的检测和分辨率性能的显著潜在增益，又集中在开发信号处理算法以促进这些增益。我们在这里提出的是利用我们已经完成的工作（i）在现实的MIMO雷达或声纳场景中计算检测性能的方法;（ii）不需要二次训练数据的基于雷达阵列的信号处理的自适应检测技术。我们解决开放的研究问题，其解决方案将促进工业开发的MIMO雷达的概念。具体而言，这些措施是：（i）相关控制恒定幅度MIMO波形的设计;（ii）能够在未知杂波统计的环境中以及在单个TR/RX对之间的有限带宽通信信道的约束内工作的自适应接收机算法的开发。这项工作的另一个新方面将是在声纳环境中应用和评估MIMO概念。我们提出的是一个严格的通用方法来理解和应用MIMO检测。将使用目标和介质的详细计算机建模技术，在雷达和声纳应用中对结果进行测试和验证。在声纳的情况下，他们也将与测量数据进行测试。
