We describe measurements of radio frequency interference (RFI) in the 1200-1800 MHz band as observed from NASA's P-3 research aircraft during a flight along the Mid-Atlantic coast of the U.S. at altitudes of 2,000 and 20,000 ft. Both power spectra and coherently-sampled waveform data were obtained. Our results indicate that the spectrum below 1400 MHz is typically dominated by pulses from ground based radars, which, while very strong, individually have transmit duty cycles of on the order ofdoi:10.1109/igarss.2003.1294237 fatcat:w55oelw4ffepfixvkdvi7qwmii
