摘要:
无源雷达系统是基于机会照射源对目标进行定位、跟踪甚至识别的系统，这种雷达系统具有先进的系统架构与 算法，应用前景十分广泛。本文提出一种基于地面数字电视广播信号的无源雷达用于车辆定位与跟踪的技术。首先分析 DTMB （Digital Television Terrestrial Multimedia Broadcasting）信号作为非合作照射源的优势，提出了基于 DTMB 信号的无源雷达目标 定位与跟踪的算法，然后通过构建试验平台，实地测量数据，利用 MATLAB 设计实时数据处理算法对移动车辆的运动状态进 行定位与跟踪。实验结果表明，利用无源雷达进行移动车辆的定位与跟踪是完全可行的。
Abstract:
Abstract: Passive radar systems exploit non-cooperative illuminators of opportunity to detect and track targets in areas of interest. Because of its multistatic system architecture and the application of the advanced positioning algorithms, the benefits offered by passive radar are numerous. In this paper we propose a technology based on passive radar using the DTMB signal as the non-cooperative illuminators. Firstly, we elaborate the advantages of the DTMB being used as the non-cooperative illuminator. Then an experimental passive system is constructed to perform real measurements in realistic environments. Post-processing software is designed based on the high-resolution channel parameter estimation algorithm – SAGE (Space-Alternating Generalized Expectation-maximization) to process data. The results obtained demonstrate that it is feasible to use passive radar based on the DTMB signal to detect and track the moving scatterers, such as vehicles.
