How thermal drone search and rescue works: LWIR emissivity, Mylar space blanket reflection, diurnal thermal crossover, Johnson GSD criteria, FLIR SAR settings, and White Hot vs Ironbow SAR palettes.
A grid the aircraft does not fly is a gap. IAMSAR sets coverage as sweep width over track spacing, and the pattern has to match how well the datum is known.
What optimizing a drone search and rescue flight actually changes, why forest canopy makes it hard, which levers help, and how to check a detection claim before relying on it.
