Abstract
Two-dimensional direction-of-arrival (DoA) estimation in azimuth and elevation via radar systems equipped with uniform rectangular arrays (URAs) will play an important role in various application areas—most distinctively in future urban air mobility settings with unmanned aerial vehicles. A key factor is the fast and reliable provision of target detections in terms of range and DoA for safe autonomous operation of the vehicle using on-board antenna arrays with compact installation size. The authors present a technique for improving the performance of DoA estimation using compressive sensing in conjunction with multiple-input multiple-output arrays with electronically steered beams in the transmit direction. The simulation study investigates the impact of different design considerations on radar signal processing performance. An optimisation of a radar system using electronic beamsteering in the transmit domain is presented numerically. Based on the architecture of the URAs used, performance and detection accuracy can be improved.
通过配备有均匀矩形阵列(URA)的雷达系统进行方位角和仰角的二维到达方向(DoA)估计,将在各种应用领域发挥重要作用,尤其是在未来使用无人驾驶飞行器的城市空中移动环境中。其中一个关键因素是利用安装尺寸小巧的机载天线阵列,快速可靠地提供目标探测距离和 DoA,以保证飞行器的安全自主运行。作者提出了一种提高 DoA 估计性能的技术,该技术采用压缩传感技术,并与在发射方向具有电子转向波束的多输入多输出阵列相结合。模拟研究调查了不同设计考虑因素对雷达信号处理性能的影响。在发射域使用电子波束转向的雷达系统优化以数值形式呈现。根据所使用的 URA 结构,性能和探测精度都可以得到提高。
