ARLINGTON, Va., 10 March 2013. Government electro-optical sensor researchers will brief industry this week on an advanced initiative to develop fundamentally new avionics and vetronics 3-D electro-optical sensors for target identification and tracking.

Scientists at the U.S. Defense Advanced Research Projects Agency (DARPA) in Arlington, Va., will host a technical overview and proposer’s day conference from 8 a.m. to 2 p.m. this Friday, 15 March 2013, on the second phase of the Military Imaging and Surveillance Technology-Long Range (MIST-LR) program.

The MIST-IR program seeks to develop new kinds of electro-optic sensing for aircraft and ground vehicles to detect and track people and other targets. The program focus is on long-range geometric and 3-D imaging to characterize targets beyond the physical-aperture diffraction-limit of the receiver system.

Industry briefings will be at the DARPA Conference Center, 675 North Randolph St., in Arlington, Va., to provide information on the status and capabilities developed under the MIST program and promote additional discussion.

Those attending will receive details from the first phase of the MIST-LR program and related efforts; hear questions and answers from potential MIST-LR proposers; and have an opportunity to discuss their capabilities and teaming opportunities.

DARPA conducted an industry briefing and released a formal solicitation for the first phase of the MIST-IR program in February 2012. The agency has not publicized any contract awards that may have been made.

The MIST-IR program’s second phase will concentrate on new sensing methods and techniques based on computational imaging, synthetic-aperture imaging, digital holography, and multi-static laser radar (ladar).

Optical sensors available today can help identify targets, but their sizes and operational ranges can be limiting, DARPA officials say. The MIST-LR program seeks to develop new sensing methods that address physical aperture of the imaging receiver, the effects of atmospheric turbulence, performance of the receiver array, the power of the illumination source, and the image formation algorithms are the primary defining characteristics of active imaging systems.

The first phase of the MIST-IR program involved a formal preliminary design, at the system and subsystem level to establish the basis for a detailed design; experimental and simulation data validating the concept, approach, and link budget; demonstration of critical hardware and software subsystems; phenomenology measurements; evidence that the proposed designs can be manufactured affordably; and written descriptions of the architecture, design, and subsystems.

Phase 2, meanwhile, will complete the system and subsystems design, and integrate components into one laboratory system to emulate a small-scale imaging capability, as well as demonstrate processing and control software for final system designs. A future third phase will develop and demonstrate a prototype package on an aircraft or ground test range.

Those interested in attending the MIST-IR phase-two briefings should register no later than this Wednesday, 12 March 2013, by email to BAA-13-27@darpa.mil. Put MIST Conference Registration in the subject line. A SECRET security clearance is required to attend.
