Paper Abstract

The WILDCAT sensor is being developed to provide long range, laser standoff detection of chemical agent vapor and aerosol clouds by DIAL and range-resolved cloud mapping by DISC. The sensor is composed of two major subsections, including a telescope/gimbal assembly and a laser/beam diagnostics section that are held in alignment with a surrounding truss system and electrically-actuated, closed-loop mirrors. The entire assembly is integrated into a transportable, 30 ft long container that is field operable. The laser is a pulsed CO2 type with output energies of 1 J at a repetition rate of 100 Hz and it uses an agile grating to access approximately 60 lines over the 9.2 - 10.7 micrometers band, also at a 100 Hz rate. The telescope/gimbal subsection is composed of a 60 cm dia telescope mounted to a yoke gimbal which provides for full hemispherical scans. The sensor includes a data acquisition system composed of 12 bit, 30 MHz analog-digital converters and a digital signal processor that maintains a running average data stream for each range bin. Algorithms allow for real-time data processing and radar displays of chemical concentration.
