Single-Sensor Localization of Moving Sources Using Diffusion Kernels

Source localization is a common problem in various fields and has applications in both military and civil sectors. Localization of acoustic sources generally requires a few microphones, but it is also possible to use a single microphone and data that was recorded in advance in the same environment. Unfortunately, existing single microphone localization methods are restricted to acoustic sources that have a fixed location. In this research, we introduce a supervised method for estimating both the location and velocity of a moving acoustic source, using a single microphone, based on a diffusion maps approach. The signal, transmitted by the source during its movement, is received by the sensor. The received signal is divided into time frames. The trajectory, formed by the movement of the source during the frame, is approximated by a linear movement segment. Each frame is inspected individually for estimation of the location and velocity. The performance of the proposed method is examined by various simulations investigating the sensitivity to different hyperparameters (e.g., frames length), variables (e.g., speed and direction), and conditions (e.g., reverberation time). *M.Sc. student under the supervision of Prof. Israel Cohen. Eran Zeitouni received his B.Sc. degree (cum laude) in Electrical Engineering from the ORT Braude College of Engineering, Karmiel, in 2012. From 2011 to 2017, he was a researcher and a system engineer at a technological unit of the Israeli Defence Forces (IDF). Since 2018 he has been a Teaching Assistant and a Project Supervisor with the Signal and Image Processing Lab (SIPL), Electrical & Computer Engineering Department, Technion – Israel Institute of Technology, Haifa. Currently, he pursues his M.Sc. degree in Electrical & Computer Engineering from the Technion – Israel Institute of Technology, Haifa. Zoom meeting link: https://technion.zoom.us/j/96390522948
