Abstract

Radar sensors are widely used in intelligent transportation systems. The performance of radar sensors in practical setups depends on many factors, such as sensor specifications, choice of locations, height and orientations of sensor installation. Currently, most of these choices are made by a "rule of thumb". In many cases, trial and error changes of settings are required and several rounds of on-site measurements and adjustments are incurred, which are both inefficient and costly. To overcome these problems, this paper reports a 3D virtual radar system that can accurately predict and evaluate the performance of actual radar sensors using a standard computer. The proposed system builds upon a 3D virtual model of real world. It allows users to freely enter specifications for radar sensors and the underlying algorithm can efficient calculate and represent graphically in the 3D model by the coverage area of the chose radar sensors at the specified location in the virtual world. Comparison with experimental data obtained using hardware testbeds shows the result obtained by the virtual radar system is accurate.

一种用于交通监控雷达传感器性能预测与评估的三维虚拟雷达系统

雷达传感器在智能交通系统中有着广泛的应用。雷达传感器在实际安装中的性能取决于许多因素，如传感器规格、位置选择、传感器安装的高度和方向。目前，这些选择大多是根据“经验法则”做出的。在许多情况下，需要尝试和错误地改变设置，并且需要进行几轮现场测量和调整，这既低效又昂贵。为了克服这些问题，本文报道了一个三维虚拟雷达系统，该系统可以在标准计算机上准确地预测和评估实际雷达传感器的性能。该系统建立在现实世界的三维虚拟模型之上。它允许用户自由输入雷达传感器的规格，底层算法可以根据所选雷达传感器在虚拟世界中指定位置的覆盖面积进行高效计算，并在三维模型中图形化表示。与硬件试验台的实验数据对比表明，虚拟雷达系统的仿真结果是准确的。
