Handheld Concealed Weapons Detector Development
Technical work on the contract was completed two years later, 31 August 2002, with the delivery of 16 second-generation prototype units to AFRL and NIJ for user evaluation. An additional 4 units were prepared and delivered in September. The National Institute of Justice (NIJ) and the Air Force Research Laboratory (AFRL) initiated the program in response to requests from various law enforcement agencies across the country for a cost-effective weapons detection system that would be capable of
... cting both metallic and non-metallic weapons from a stand-off distance of up to 10 meters. The primary application of these detectors will be to enhance the safety and effectiveness of community police officers around the nation by: 1) establishing reasonable grounds for searches of suspects; 2) scanning suspects for both metallic and nonmetallic weapons at safe stand-off distances during arrests; and 3) searching for both metallic and nonmetallic weapons on cooperative subjects at courthouse entrances and other police-controlled portals. Building on Jaycor's original prototype design (also sponsored by AFRL and NIJ) the scope of the effort included a number of design modifications that helped to extend the stand-off distance from 12 feet out to 25 feet, reduce the false alarm rate (both false positive and false negative), and make the unit more ergonomically functional. The program consisted of an initial phase of development and testing, followed by a phase of design, additional testing, fabrication and assembly. A number of formal presentations were made at the annual AFRL/NIJ Program Reviews held during the course of the effort, as well as at the SPIE Conference on Enabling Technologies for Law Enforcement and Security held November, 2000 in Boston, Massachusetts, and the SPIE Aerosense 2002 Conference held in May of this year in Orlando, Florida. A demonstration booth was also set up at the Force Protection Equipment Demonstration (FPED III) held at Quantico Marine Corps Base, Virginia in May, 2001.
