Sector Scan Sonars / Overview
Sector scan sonars provide radial coverage around a vehicle, usually for collision avoidance purposes. Their traditional display is most familiar to us as a PPI (plan position indicator) or “radar-scope” format image, showing radial range and direction to targets, with strong targets showing up as “blips”.
GeoDAS supports Sector Scan sonars via GeoDAS-PPI, which allows not only control and traditional PPI display, but also full geocoding and real-time mosaicking of the sector-scan data.
