摘要： A method is provided for detecting interference in a radar system. The method includes transmitting, by a transmitter of the radar system, a sequence of radar pulses at a regular interval with a rest period following each radar pulse of the sequence of radar pulses. The transmitter is disabled during each rest period. A receiver is enabled to receive reflected radar pulses from a target during the rest period following each radar pulse of the sequence of radar pulses. Some of the radar pulses are selected to be omitted and not transmitted. The receiver is still enabled during the rest periods following the omitted transmission pulses. Any reflected pulses received during the rest periods following the omitted transmission pulses may be an indication of a targeted interference of the radar system. In another embodiment, a radar system is provided.

摘要： In an ultra-wideband (UWB) communication network, a controller anchor changes which anchor of a group of anchors serves as initiator for each of multiple ranging rounds. Based on the capabilities of the anchors in the UWB communication network, the controller selects among multiple modes for designating which anchor serves as initiator for each ranging round. In a first mode, the anchors take turns serving as the initiator for successive ranging rounds in round robin fashion. In a second mode, the anchors randomly take turns serving as the initiator for ranging rounds. By dynamically selecting an initiator for each ranging round, launching a successful jamming attack becomes significantly more complicated.
