Interaction of Supernova Ejecta with Nearby Protoplanetary Disks
, 2007 The early Solar System contained short-lived radionuclides such as 60Fe (t1/2 = 1.5 Myr) whose most likely source was a nearby supernova. Previous models of Solar System formation considered a supernova shock that triggered the collapse of the Sun's ...

Detection and jamming low probability of intercept (LPI) radars
, 2006 An increasing number of LPI radars are integrated into integrated air defense systems (IADS) and modern platforms and weapons, such as anti-ship missiles, and littoral weapon systems. These LPI radars create a requirement for modern armed forces to develop new techniques, strategies, and equipment.

Extremely High Frequency (EHF) Low Probability of Intercept (LPI) communication applications
, 1990 A Commander-in-Chief U.S. Pacific Fleet letter to the Chief of Naval Operations, dated September 12, 1989, contains a Command and Control Studies and Analysis Program (C2STAP) proposal for EHF line-of-sight communications. The purpose of this thesis is to address several of the issues raised by the C2STAP proposal by providing: an analysis of the ...

Analysis of low probability of intercept (LPI) radar signals using the Wigner Distribution
, 2004 The parameters of Low Probability of Intercept (LPI) radar signals are hard to identify by using traditional periodogram signal processing techniques. Using the Wigner Distribution (WD), this thesis examines eight types of LPI radar signals. Signal to noise ratios of 0 dB and -6dB are also investigated.
