HIGHRESOLUTION AUTOMOTIVE RADAR/SENSOR TECHNIQUES FOR DETECTING LOCATION AND ANGULAR SPREAD OF RADIO SOURCES

研究和发展了在汽车雷达（阵列天线）中同时检测目标位置和范围的高分辨辐射源估计技术。此外，用于有效地指定的位置的技术已被调查时，有一个发射源在近场。结果，已经证实，每个入射波的到达角和角扩展都可以通过简单的方法来估计。此外，对近场源定位方法进行了改进，使其在辐射源为宽带信号时也能有效定位，并验证了其有效性。

High-resolution emitter source estimation technique to detect boththe position and extension of the target in the automotive radar(array antenna) has been researched and developed. Also, the technique for efficiently specifying the position has been investigated when there is an emitter source in the near field. As a result, it has been confirmed that both the angle of arrival and the angular spread of each incoming wave can be estimated by a simple method. Moreover, the near-field source localization method is improved so as to be available even when the emitter source is a broadband signal, and its effectiveness is shown.
