Abstract

Longwave infrared (LWIR) and midwave infrared (MWIR) UAV signature data have been acquired and analyzed in collaboration with L3 Technologies, and we present intensity and root sum square delta T for two rotorcraft unmanned aerial vehicles (UAVs), including the popular DJI Phantom 4 and DJI Inspire, at 0-, 45-, and 90-deg aspect angles. Signature measurements are conducted in the field with clear sky, cloudy, and land backgrounds. We compare MWIR values to that of LWIR for the following criteria: aspect angle, background type, and UAV type.
