Abstract

In this paper, we introduce the novel synthetic aperture secondary (SAS) radar positioning technique for the localization of a vehicle. The SAS technique is based on a frequency-modulated continuous wave (FMCW) secondary radar concept where the interrogating radar signal is reflected coherently by a backscatter transponder. It will be shown that SAS positioning is a very efficient way to combine the data of wireless positioning systems with the data from assisting sensors. Our novel SAS local positioning technique outperforms the usual integrated or hybrid navigation approaches based on multilateration notably. A 5.8-GHz wireless local positioning system has been built to test our SAS concept. The synthetic aperture is set up by a moving vehicle. Aperture points are determined with the use of gyroscope and tachymeter sensor data. A newly developed SAS reconstruction algorithm estimates the most likely transponder positions. Based on these estimations, the vehicle determines its position with an accuracy of approximately 5 cm even in complex multipath environments.

基于合成孔径二次雷达成像方法的后向散射应答器定位
本文介绍了一种用于车辆定位的新型合成孔径二次雷达(SAS)定位技术。SAS技术基于调频连续波(FMCW)二次雷达概念,其中询问雷达信号由后向散射应答器相干反射。SAS定位是将无线定位系统的数据与辅助传感器的数据相结合的一种非常有效的方法。本文提出的SAS局部定位技术明显优于一般的基于多重定位的综合或混合导航方法。已经建立了一个5.8 ghz无线本地定位系统来测试我们的SAS概念。合成孔径是由移动的车辆设置的。孔径点是利用陀螺仪和测速仪传感器数据确定的。一种新开发的SAS重建算法估计最可能的应答器位置。基于这些估计,即使在复杂的多路径环境中,车辆也能以大约5厘米的精度确定其位置。
