Abstract:

This report contains results of spectrum occupancy measurements made of the 2700-3100 MHz radar bands in the Los Angeles, CA, area. Approximately 500 sets of measurements were made, which included peak pulse amplitude, as well as the number of pulse counts at three threshold levels measured in 1 MHz frequency increments. These measurements have been combined and are displayed in this report in graphs showing the maximum, average, and minimum amplitude and pulse counts in 1 MHz frequency increments 400 samples. These measurements were made for the Federal Aviation Administration FAA by the Institute for Telecommunication Sciences ITS using the Radio Spectrum Measurement System, a computer-controlled spectrum analyzer system. The measurements will be used to quantify the S-band electromagnetic environment expected to be encountered with NEXRAD, a doppler weather radar currently under development. Author
