| Outline of Final Research Achievements |
It is confirmed that propagating phases of non-coherent waves are properly analyzed in image diagnostics with adaptive-array technique. First the wave propagation was detected in snap-shot measurements, and then was done using a software-defined radio system with date streaming in high time resolution. The receiving lobe of the non-coherent wave could be analyzed with similar spatial resolution of the coherent-wave radiation lobe. Here a broadband thermal noise source was used as a non-coherent emission source. A Capon method remarkably reduces the receiving lobe area, compared to that with the normal beam-forming method. A looped antenna has been considered as a phased-array receiver to find the emitting position precisely. A number of the looped antennae could be prepared in the limited space, taking advantages for the precise position finding.
