Abstract
One aspect of the present disclosure relates to a system for detecting aerial vehicles, the system comprising a continuous-wave coherent lidar unit selectively operable in at least a detection mode and an imaging mode. The continuous-wave coherent lidar unit is configured, when operated in the detection mode: to emit and/or scan a continuous-wave laser detection beam towards a detection target region, and to receive a return laser signal from the detection target region by coherent detection. The system is configured to process the return laser signal, received by the continuous-wave coherent lidar unit when operated in the detection mode, so as to detect one or more signal features indicative of the presence of an aerial vehicle in the detection target region, and to determine one or more attributes of the said aerial vehicle in the detection target region from the detected one or more signal features. The continuous‐wave coherent lidar unit is further configured, when operated in the imaging mode to scan a focused continuous‐wave imaging laser beam across an imaging target region, and to receive respective return laser signals from respective positions within the imaging target region by coherent detection. The system is configured to process the return laser signals, received from respective positions by the continuous‐wave coherent lidar unit when operated in the detection mode, to create at least one two‐dimensional image of the imaging target region.
