(U) Satellite Threat Warning and Attack Reporting System (STW&ARS)

Overview: (U)
(U) Phillips Laboratory's threat warning and attack reporting (TW/AR) program is regarded as a counterspace protection technology whose purpose is to develop and demonstrate essential technologies and capabilities for space assets.  Principal threat environments are those created potentially by sources of electromagnetic and optical directed energy weapons (DEW), or electromagnetic and optical sources capable of  producing sufficient energy to disrupt, deny, or degrade the operational effectiveness of US space assets.  

Description: (U)
(U) Initial efforts will concentrate on development of sensors and appropriate signal processors capable of: (1) detecting and recognizing potential adversary acquisition and tracking signatures at selected orbital altitudes and inclinations; (2) providing  electro-optical jamming and upset threat warning; and (3) providing deliberate RF/HPM and laser threat characterization.  

(U) Requirements for the sensors and signal processors will be developed through an interactive process with the operator and user community, the sensor development community, and the satellite development Program Offices tasked with threat warning and attack reporting mission requirements.  Supporting studies and analyses for CONOPS and system architectures will provide additional TW/AR subsystem requirements in terms of threat detection, characterization, location, and reporting requirements.

(U) Prior efforts, funded under PE63438, have developed preliminary concept definitions for RF/HPM and laser detection and reporting for space applications.  Critical technology issues have been identified as a function of the originally established, comprehensive mission requirements.  An iterative process to refine mission requirements in light of technical capabilities, better definition of CONOPS, and utility of TW/AR information to the operator and user is underway.

(U) Proof-of-concept detectors and sensors are planned to be flown on MIGHTYSAT or ISTD spacecraft in FY00-03.  Extensive ground demonstration including possible aircraft flights will precede the space flights.
