Covey

A swarm of Lark radar nodes images a city block while overflying it. This is a navigable replay of a ratified collect: the 3D world is reconstructed from the mission geometry, the radar image is streamed from the Lark simulation.

Each node sees the same targets at a different range. The spread across S1/S2/S3 is what a distributed collect fuses to localize. Use the tabs over the SAR image to isolate a node.

Method

Positions are reconstructed from the flight track and synced to the SAR image by capture time. The imaged window (green) glides east with the node; the SAR panel shows that footprint.
