Received signal power measurements were performed on the Common Air Route Surveillance Radar (CARSR) operating in the 1300–1370 MHz band in Parker, Colorado and on the Airport Surveillance Radar (ASR 9) operating in the 2700 2900 MHz band in Platteville, Colorado. The measurements were taken along five radials extending from each radar transmitter. Four or five fixed locations were chosen along each radial where predicted received signal power varied from relatively strong to weak levels. Multiple peak received power measurements were made at each location to provide statistically significant results. In another effort, these measurements will be used to validate spectrum usage contours and the methodology used to generate them as developed by the Office of Spectrum Management (OSM) of the National Telecommunications and Information Administration (NTIA).
