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

研究和开发了用于汽车雷达（阵列天线）中目标位置和扩展检测的高分辨率辐射源估计技术。此外，本文还研究了近场有发射源时的有效定位技术。结果表明，每个入射波的入射角和角传播都可以用一种简单的方法估计出来。此外，对近场源定位方法进行了改进，使其在发射源为宽带信号时仍然有效，并证明了其有效性。

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.
