The Single Channel Ground and Airborne Radio System




The Single channel ground and airborne radio system (SINCGARS) ( ) is a new family of VHF-FM combat net radios which provides the primary means of command and control for infantry, armor and artillery units. SINCGARS is designed on a modular basis to achieve maximum commonality among the various ground and airborne system configurations. A common receiver transmitter (RT) is used in the manpack and all vehicular configurations. SINCGARS family of radios has the capability to transmit and receive voice, tactical data and record traffic messages and is consistent with NATO interoperability requirements ( ). The system operates on any of the 2320 channels between 30-88 megahertz and is designed to survive in a nuclear environment. Communications security (COMSEC) ( ) for the basic radio is provided by use of the VINSON device. An integrated COMSEC version of the SINCGARS is currently in production. SINCGARS is operable in a hostile environment through use of electronic counter countermeasure. SINCGARS replaces the current standard manpack and vehicular radios, AN/PRC-77 and AN/VRC-12 family, respectively.

SINCGARS provides commanders with a highly reliable, secure, easily maintained combat net radio (CNR) that has both voice and data handling capability in support of command and control operations. SINCGARS, with the internet controller, provides the communications link for task force XXI. SINCGARS configurations include manpack, vehicular (both low and high power), and airborne models. COMSEC is integrated in currently produced versions of the ground and the airborne radios, and the system improvement program models providing upgrades to enhance operational capability in the tactical internet environment, and the advanced system improvement program models that are of a reduced size and weight provide further enhancements to operational capability in the tactical internet environment.

, , ? The radars fall into two general categories: surveillance and fire control.
? Surveillance includes early warning, target-acquisition, and height-finding radars ( ).
? The radar essentially consists of six components: transmitter, receiver, directional antenna, timer (), indicator and power supply unit ( ).
? The phased-array radar antenna is positioned at an angle, relative to the horizontal plane, during emplacement of the radar set. When fully elevated, the antenna can be trained ( ) in azimuth by means of a motor driven pedestal assembly ( ) which supports and rotates the entire radar shelter ( ).
The IFF group consists of an electronically steerable IFF antenna array ( ) located on the antenna lens ( ) assembly, and an IFF interrogator set ( ). The IFF group is controlled and timed by the IFF interface unit in the control unit group.
