ISR missions aren’t solely launched from satellites and airborne vehicles. Ground-based hyperspectral systems silently scan the landscape for many of the same things that their airborne counterparts would. Particularly useful for base protection and homeland security, these sensors rapidly look at the chemical composition of anything within the field of view. A high degree of discrimination allows these ‘point-and-stare’ systems to call attention to anything that matches a particular spectral signature. This differs markedly from most other techniques, which focus on visual appearance and don’t have the same level of discrimination. A companion to Headwall’s point-and-stare solution is the motorized ‘pan-and-tilt’ system that provides 360-degree coverage and precise control of position, speed, and acceleration.
Headwall's hyperspectral sensors can be configured in either of the following manners:
