PPT-Passive Radar with LWA1

J Helmboldt NRL LWA Users Meeting Albuquerque NM July 27 2012 Introduction Passive radar is a technique that uses existing transmitters eg FM radio broadcasts to detect and determine range to reflections from objects terrain andor ionosphere. In a radar bin it provides a measure of the variability of the mean radial velocity estimates movement due to wind shear turbulence andor the quality of the velocity samples The proper use of Spectrum Width can help the severe thunderstorm and torna Sheena .
