摘要： A radar system for monitoring a region of interest (ROI), wherein the radar system includes an antenna arrangement for emitting and receiving electromagnetic radar radiation and a signal processing arrangement for generating signals to be emitted in operation as corresponding electromagnetic radar radiation from the antenna arrangement to the region of interest (ROI) and also for processing received signals resulting from reflections of the electromagnetic radar radiation from one or more objects present in the region of interest (ROI). The radar system is arranged such that at least one of the one or more objects present in the region of interest (ROI) includes a radar radiation reflecting target. The signal processing arrangement is operable to determine a component of the received signals corresponding to the radar radiation reflecting target, and to monitor over a period of time changes in the component of the received signals, wherein changes in the component greater than at least one threshold value are indicative of a malfunction of the radar system and/or a change in a status of the region of interest (ROI) that is potentially hazardous. The radar system is operable to compare additional sensor signals, wherein the additional sensor signals are other than the received signals resulting from reflections of the electromagnetic radar radiation from one or more objects present in the region of interest (ROI), against one or more associated threshold values to determine whether or not a malfunction or hazardous situation has arisen, and to fuse the additional sensor signals with an indication of the malfunction or hazardous situation as generated by the component of the received signals. The radar system is arranged to employ cued search capabilities for processing the received signals corresponding to the radar radiation reflecting target and the additional sensor signals.

摘要： A method of calibrating a multiple-input and multiple-output radar system is provided. The radar system includes a transmitting array and a physical receiving array. The transmitting array includes a first transmitter and a second transmitter spaced a distance away from the first transmitter. In the method, a waveform signal is transmitted firstly from the first transmitter and then from the second transmitter, such that receiving sub-apertures of the physical receiving array overlap with receiving sub-apertures of a virtual receiving array. The waveform signal is received at the physical and virtual receiving arrays. Subsequently, deviations in response between the physical receiving array and the virtual receiving array are computed. Effective positions of the first transmitter and the second transmitter are assessed, based upon the computed deviations. Setup calibrations needed for the multiple-input and multiple-output radar system are then determined, in order to reduce the computed deviations.
