(U) Long Range Dual Band Transportable Radar (LRDBTR)

(The effects of any budget/program decisions made since the information was collected during 1997-98 are NOT reflected in the National Security Space Road Map (NSSRM).)

Overview: (U)
(U)  Long Range Dual Band Transportable Radar (LRDBTR) is an enhanced version of the COBRA GEMINI radar designed to provide longer search and track range capability of multiple targets such as low trajectory theater missiles, tactical ballistic missiles, cruise missiles, and aircraft.

Description: (U)
(U) LRDBTR is a surface based (land or sea) high power, dual band, transportable, imaging dish radar operating at two frequency bands: S- and X-band capable of up to a 2000 km range. 

(U) LRDBTR can simultaneously provide a surveillance fence and collect highly precise metric, signature, and imaging data on targets of interest such as low trajectory theater missiles, tactical ballistic missiles, cruise missiles, and aircraft. Given the range
and sensitivity improvements, LRDBTR will also be capable of intercontinental ballistic missile (ICBM) detection and tracking. 

(U)  LRDBTR uses the same proven capabilities of the COBRA JUDY, the legacy system from which COBRA GEMINI was derived. The enhancements will consist of a combination of:

 -- larger diameter radar dish reflector; 
 -- increased transmitter power; and 
 -- improved signal processing.

(U) The enhancements will be applied to provide the optimum range improvement at the lowest design tradeoff costs.
