Mobile Blackbody Calibration Source

To address the United States Air ForceÆs (USAFÆs) need for a mobile platform outfitted with an array of large-aperture blackbody sources as a field reference for calibrating radiometric imagers, Intellisense Systems, Inc. (Intellisense) proposes to develop a new remotely operated, mobile blackbody calibration source (MoBB). This system is based on a mobile remote-controlled command trailer outfitted with rugged large-area blackbody source panels with extended wireless capabilities, weather sensing, thermal control, and self-sustaining power. A long-range optical calibration probe (OCP) will calibrate this system wirelessly. Specifically, the innovations in using an array of heating/cooling elements over a high emissive coated aluminum honeycomb core provides a lightweight, mechanically robust, and cost-effective blackbody calibration source to reach large-area apertures (24 in. by 24 in.) and mount 8 panels on a mobile platform. The OCPÆs long-range optical thermal calibration will enable the USAF to perform self-calibration and temperature reading verification remotely at long distances (>1000 yd), which saves labor and time while reducing traffic. The MoBB can connect with distant operators (>1000 yd) on mobile devices and personal computers for remote control and temperature readings with time-stamped data. MoBB is also fully motorized with environmental sensors to detect inclement weather and autonomously protect its blackbody panels without requiring constant supervision, thus reducing operational requirements and maintenance. Combined with a fuel-power electric generator, the MoBB can continuously operate for long periods of time (40 hrs) without the need of external power. As a result, the MoBB system meets USAF requirements for a next-generation field calibration suite for radiometric sensors. In Phase I, Intellisense will demonstrate the feasibility of MoBB technology by mounting large-frame blackbodies to a mobile structure and evaluating the blackbody and mobile platform used in MoBB. Intellisense will also design MoBBÆs remote control operations and develop a plan for a Phase II prototype, determining its operating and maintenance requirements for the upkeep of the system. In addition to delivering the prototype in Phase II, Intellisense plans to assemble a mobile platform or trailer which will be towed by a government pickup truck and capable of housing the required blackbodies.
