October 2019 | NTIA Technical Report TR-20-543
Abstract: Received signal power measurements were performed on the Common Air Route Surveillance Radar (CARSR) operating in the 1300 1370 MHz band in Cedar City, Utah, and on the Airport Surveillance Radar (ASR 9) operating in the 2700 2900 MHz band in Trout Creek, Utah. The measurements were taken at sites relatively far from each radar transmitter. The measurement locations represent different predicted propagation modes (such as line-of-sight, diffracted, tropospheric scatter, etc.) and varying predicted received signal powers (from strong to weak). Distances from the transmitter to the measurement locations varied from roughly 56 km to 141 km for the ASR-9 and 17 km to 194 km for the CARSR. Multiple peak received signal 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).
