Abstract(in English) | Lightning Research Group of Osaka University (LRG-OU) has been developing VHF Broadband Digital Interferometer (DITF) to image precise lightning channels and monitor lightning activity widely. The feature of broadband DITF is its bandwidth (from 25MHz to 100MHz) and implicit redundancy for estimating VHF source location. Since the VHF broadband DITF own the superiority to image lightning channels with rather short base line, LRG-OU considers an application of BDITF to the space-borne measurement system. One of the possibilities to realize the idea is a Panel Extension Satellite (PETSAT). PETSAT may consist of some independent panels. Each panel will be designed to own individual function and the configuration of PETSAT is adjustable depending on the objectives. Since it is shown that the short baseline of DITF could accomplish the high time and space resolution for VHF source locations, we can reach an idea of VHF broadband DITF operation on PETSAT. PETSAT is planed to be a low altitude satellite about several hundred kilometers from the ground, and the locations accuracy of 0.01 radians may provide us the sufficient and unique opportunity to discriminate between the active thundercloud from non active ones by satellite observations. We are expecting to launch PETSAT by 2007. |
