PAVE PAWS Radiation Decays Exponentially in Lossy Materials

摘要

Dr. Rick Jostes asked me to give a talk for a National Research Council committee that is investigating aspects of a phased-array radar named PAVE PAWS. Dr. Jostes suggested that I discuss the relation of statements by Prof. Kurt Oughstun to my recent work on exponential decay of radiation in lossy materials. With that incentive, I found that most of the 88-years' of precursor literature is irrelevant to PAVE PAWS. Indeed, I will first list incident pulses mentioned by this literature, but whose spectra are not separated from DC. (DC is a synonym for frequency=0.) Such pulses cannot be produced by PAVE PAWS, which broadcasts from 420-450 MHz or, equivalently, 435 MHz + /- 3.5%. I will also list parts of the literature that regard these types of pulses that PAVE PAWS cannot produce. This executive summary will also sketch answers to questions asked during my talk. This report's section after the transparencies will substantiate the executive summary.
