HR-RTIS: High-Resolution Real Time Imaging Sonar Sensor.

For autonomous vehicles, sonar sensors can pose a real alternative to optical sensing techniques such as laser scanners and 3D cameras in situations where these optical techniques fail. The failure of these optical systems can be caused by medium distortions such as dust or fog, or sensor contaminations such as mud splashes. In the CoSys research group we develop advanced 3D sonar sensors for industrial applications, which are currently being validated in various industrial application niches. During this proposed STIMPRO project we propose to expose the uncover the dynamic range in the strengths of echoes created in relevant industrial environments and their spatial distribution in that environment. To this extend, we propose a high-resolution microphone array consisting of 1000 microphones, which will allow the creation of high-resolution and high dynamic range 3D sonar images. The sensor will provide us with essential insights into the reflective properties of relevant environments and will allow us to improve the low-cost sensors which we are famous for worldwide.
