Advanced technology improvements for the Firefinder ground weapon locating radars that will extend system service life and significantly reduce customer life cycle costs are being incorporated into the AN/TPQ-37 radar platform. In conjunction with the U.S. Army, ThalesRaytheonSystems (TRS) has developed the AN/TPQ-37 Reliability, Maintainability Improvements that are being incorporated into fielded U.S. Army inventory assets allowing the combat proven system to remain the mainstay of long range artillery well into the 21st Century. The radar upgrade will provide significant improvements over the current fielded system by providing new, state-of-the-art electronics in the form of an aircooled modular transmitter and new radar processor.
