AN/TPQ-37 Firefinder radar

A typical AN/TPQ-37 system consists of the Antenna-Transceiver Group, Command Shelter and 60 kW Generator.

Upon detecting a possible incoming round, the system verifies the contact before initiating a track sequence, continuing to search for new targets.

The incoming round/rocket is tracked during its initial upward/launch trajectory (i.e., the linear portion of its flight path) prior to reaching apogee.

A computer program analyzes the track data and then extrapolates the round's point of origin.

Capabilities Specifications Features Before acquisition by Raytheon, the Hughes Aircraft Co. developed the AN/TPQ-37 Firefinder radar at its facility in Fullerton, California, and manufactures it at its plant in Forest, Mississippi.
