Images of Tire Graveyard with Reduced Resolution

Many tires can be found on the bottom of Lake Union near the APL/UW Dock. Apparently, they fall off of the sides of docks, where they are used as tires bumpers. This image shows several of these tires, in order to demonstrate the fine-scale imaging capabilities of the sonar system.

The smoothed images were created by linear interpolation in azimuth. The images were not smoothed in range. The non-smoothed images (and all images in range) were created using pixel replication.
