【摘要】 雷达实时成像系统已经被广泛的应用到各项领域中。毫米波成像雷达的显著特点是频带较宽、数据量大、实时性要求较高。这对其信号处理机设计提出了较高的要求。本文通过对毫米波成像雷达特性的分析,提出了一种基于高速数据传输与并行处理的信号处理机设计架构。基于该设计架构的硬件平台已在某型号项目中应用,实际结果验证了它的数据吞吐能力、并行处理能力以及实时成像能力。更多还原

【Abstract】 Real-time imaging radar system is widely used in many fields. The great bandwidth, large amount of data and high demand of real-time processing capability are the obvious characteristics of millimeter wave imaging radar. This is a higher demand for the design of a signal processor. In this paper, the features of a millimeter wave imaging radar is analyzed and a novel signal processor design structure is proposed based on ultra-speed data transfer and parallel process. The designed hardware platform is applied in a certain radar system. The data throughout capability, parallel processing capability and real-time imaging capability have been verified.更多还原
