Abstract

Abstract. In this contribution, the design of a multiple-input multiple-output (MIMO) radar system in 77–81 GHz range with 18 transmitting antennas and 24 receiving antennas for measuring the height profile of bulk solids in silos, is presented and discussed. The antenna array topologies are optimized by utilizing space filling fractals in order to approximate a circular shaped antenna array on a hexagonal grid. The proposed MIMO radar system achieves an angular resolution of 3.1∘ for a maximum scanning angle of ±45∘ and a side lobe suppression of 12.6 dB. The performance of the system has been evaluated by test measurements on a sand heap, showing an improved measurement accuracy compared to conventional radar level systems.

基于分形天线阵列的MIMO雷达系统在水平面测量中的应用

摘要在这一贡献中，77–81年的多输入多输出（MIMO）雷达系统的设计提出并讨论了用18个发射天线和24个接收天线测量筒仓中大块固体高度分布的GHz范围。利用空间填充分形对天线阵列拓扑结构进行优化，以近似六边形网格上的圆形天线阵列。所提出的MIMO雷达系统在最大扫描角为±45°的情况下实现了3.1°的角分辨率和12.6°的旁瓣抑制 dB。该系统的性能已经通过在沙堆上的测试测量进行了评估，表明与传统的雷达液位系统相比，测量精度有所提高。
