Abstract
A stepped frequency (SF) radar system includes a multi-channel radio frequency (RF) transceiver, a transmitting antenna, a receiving antenna, and a processor. The transmitting antenna transmits output signals from the multi-channel RF transceiver, which output signals include a plurality of signal scans. Each signal scan includes multiple output signals each having a specific frequency selected from a predetermined group of frequencies. The receiving antenna provides to the multi-channel RF transceiver input signals received thereby. The controller controls generation of the output signals to be transmitted by the multi-channel RF transceiver, and processes the input signals provided by the multi-channel RF transceiver. The controller includes a stepping modification module for randomizing an order of the output signals, within at least one of the plurality of signal scans, in order to reduce or prevent interference in the output signals.
