Common Operational Specific Emitter Identification (SEI) functionality for sustained Electronic Warfare (EW) systems

ABSTRACT: The global proliferation of modern"digital"radar systems has resulted in a two-pronged crisis for traditional electronic intelligence (ELINT) emitter identification (ID) methods: (1) the sheer increase in radio frequency (RF) emitters sharing similar characteristics and of course spectrum and (2) ever increasing digitization of radar front-ends including solid state transmitters, digital arbitrary waveform generators (DAWGS), and active electronically scanned arrays (AESAs). The former exacerbates the need for higher precision SEI while the latter unfortunately makes it much more difficult to accomplish reliable SEI using classical methods. Under this SBIR program ISL will develop new SEI techniques that overcome these problems and provide the Air Force with a capability to engage emerging emitter threats in complex RF environments. BENEFIT: The proposed SBIR program will provide the Air Force with the capability to identify and engage emerging advanced digital radar systems in complex RF environments.
