作者研制了一种基于“甚高频宽带数字干涉测量”技术的新型雷电定位监测系统。本文总结了这台甚高频宽带数字干涉仪(DITF)，以及新的观测结果。作为开发的第一步，安装了实验系统并进行了闪电观测。在这些观测中，闪电行进的成像可以在二维和/或三维获得。通过与前人研究结果和其他观察结果的比较，证实了我们的结果的有效性。对系统进行了评估，提高了系统的精度，完成了先进的系统。目前，先进的系统已经建成，并取得了初步成果。结果表明，该系统运行良好，从时间分辨率和空间分辨率两个方面较高精度地实现了VHF宽带闪电监测。
The authors have been developing a new type of lightning location and monitoring system based on a technique of “VHF broadband digital interferometry". This paper summarizes this VHF broadband digital interferometer (DITF), together with new observations. As a first step of the development, the experimental system is installed and lightning observations are conducted. In these observations, imaging of lightning progression is obtainable in two- and/or three-dimensions. The effectiveness of our results has been confirmed by the comparisons with the results of previous studies and other observations. The evaluation of the system is discussed to improve its accuracy, and the advanced system is completed. At present, the advanced system has been completed and the first result is obtained. It is concluded that the function of the system works well, and the VHF broadband DITF for lightning monitoring is accomplished with high accuracy from the aspects of time and space resolutions.
