Patent attributes
A component is disclosed for a radar system that comprises a main antenna operable to move azimuthally to sweep an area, a transmitter for transmitting pulses from the antenna and a receiver for receiving return signals. The component is operable to enable the radar system to detect a target in the presence of a wind turbine located in the area. The component comprises a plurality of auxiliary antennas and a processor for processing the return signals, the processor being operable to generate a signature of the wind turbine from return signals received by the main and auxiliary antennas in a training process, to generate model data of a target or to receive model data of the target from memory, and to test returned data for the presence of a target, and, if a target is detected, to generate data representing a detected target. A method of detecting the position of a target in the presence of a wind turbine using the radar system is also described.
