Abstract
Described in an example embodiment herein is a procedure that comprises sampling one or more channels that are not in use for a short time at certain intervals. In particular embodiments, the interval duration is irregular so as to prevent 'out of step' lock with a radar's pulses. During the sampling period, detection events are stored in terms of start time and duration. If potential radar events are detected, the channels are sampled for a longer, second interval to determine whether the detection events are indicative of radar. The length of the sampling period determines the number of samples needed to get an acceptable detection probability.
