| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | This paper proposes a beamforming method using a complex-valued spatio-temporal neural network for wideband acoustic imaging available even with a small sensor array. We combine a CVSTNN and power-inversion adaptive array (PIAA) scheme to realize a practical-resolution imaging in the azimuth direction (direction perpendicular to the range direction). Simulations and experiments demonstrate that the proposed method presents a higher resolution than conventional methods as well as a real-valued neural-network PIAA method. | |
