Improved ground moving target-indicating (GMTI) aircraft radar is aim of Army's industry request for information

Posted by John Keller

ABERDEEN PROVING GROUND, Md., 21 July 2013. U.S. Army researchers are surveying industry for the latest in wide-area ground moving target indicator (GMTI), dismount moving target indicator (DMTI) and synthetic aperture radar (SAR) technologies for a planned radar upgrade of the Airborne Reconnaissance Low, Enhanced (ARL-E) program.

The Army Contracting Command at Aberdeen Proving Ground, Md., on behalf of the Army Intelligence and Information Warfare Directorate (I2WD), has issued a sources-sought notice (W15P7T13RA753) for enabling radar technologies for an anticipated ARL-E upgrade.

The ARL-E is a multifunction, day and night, all-weather reconnaissance intelligence system for a modified Bombardier Dash 8 DCH-8 315 fixed-wing aircraft. It has a signals intelligence (SIGINT) and imagery intelligence (IMINT) payload controlled by onboard multifunction workstations.

Army officials want a new radar to enable the ARL-E aircraft to detect and classify vehicles and people on foot. The GMTI radar should be able to detect and classify vehicles at long ranges, while a DMTI mode should be able to detect and classify people on foot at mid- ranges, with SAR strip and spot modes at mid and long range.

The radar must be able to function within the aircraft speed, size, weight, and power constraints of a DCH-8 315 aircraft. Detailed draft performance requirements will be provided to interested parties. The Army wants a radar for the ARL-E aircraft that will ready to flight test within 14-16 months of contract award.

Army officials caution that this is request for information thus far, and is not yet a request for proposals. Among the companies that have shown interest in this program are Lockheed Martin Corp.; MacDonald, Dettwiler and Associates; Natel Engineering Co. Inc.; and SRI International.

Companies interested should email responses no later than 12 Aug. 2013 to

Responses should include an overview of the technology capable of meeting the requirements, a rough order of magnitude (ROM) cost; both non-recurring and recurring (unit) costs, and an approximate development timeline. Contractor should address performance against each one of the SAR and MTI ARL-E Capability Production Document (CPD) requirements.
