IMPROVEMENTS TO RADAR DETECTION IN A BROADBAND RADIO COMMUNICATION SYSTEM

摘要

Potential radar pulses are detected in a received signal waveform at a terminal of a broadband radio communication system, and a reception time is ascertained for each of the potential radar pulses. A pair of pulses is selected having respective reception times separated by an allowed pulse repetition intervals. One or more further pulses is selected that is related to the selected pair by having a respective reception time separated from the respective reception time of at least one pulse of the pair of pulses by one or more pulse repetition intervals from the set of pulse repetition intervals. At least two other pulses are discounted, that have respective reception times separated by a pulse repetition interval in the set of allowed pulse repetition intervals on the basis of not being related to the selected pair by having a respective reception time separated from the respective reception time of at least one pulse of said pair of pulses by one or more pulse repetition intervals from the set of pulse repetition intervals. The transmission of data is inhibited at least in part in dependence on the selection of the further pulses related to the selected pair.
