Paper Abstract

Northrop Grumman Aerospace Systems (NGAS) has developed the Hyperspectral Airborne Tactical Instrument (HATI), a compact airborne hyperspectral imager designed to fly on a variety of platforms and to be integrated with other sensors in the NGAS instrument suite. HATI has taken part in a variety of missions and flown in conjunction with other NGAS airborne sensors including the recently-developed NGAS 3-D flash ladar system to demonstrate a multi-sensor data fusion approach. HATI is a push-broom sensor which gathers information in the 400 nm to 1700 nm wavelength range. Its compact size allows HATI to be mounted on commercial-of-the-shelf (COTS) aerial photography stabilization platforms and on a large variety of aerial platforms. In its most recent flight season, the HATI sensor was used to gather data for applications including remote classification of vegetation, forests, and man-made materials. The HATI instrument has undergone laboratory and in-situ performance validation and radiometric calibration. This paper describes the HATI sensor and recent data collection campaigns.
