Abstract
The reconstruction of lightning discharge channel can be executed by using acoustic method [1]. Especially, it is very useful to use it in the invisible area like in the cloud. The rocket triggered lightning experiments have been carried out for winter thunderclouds [2, 3, 4, 5], and the research of the channel reconstruction has been performed to estimate the lightning striking points and to reconstruct the discharge channel [6]. Good agreements were confirmed by comparison to the photograph [7, 8]. Recently, the computation process was highly speeded up by parallel processing [9]. In this “real time reconstruction” process, a DSP-PC (Personal Computer with Digital Signal Processor) system was used, which mainly consists of a personal computer and four DSPs which are connected in a ring fashion. The high speed calculation was performed by pipe Une processing for each DSP and parallel processing for four DSPs [10, 11].
