Claim 0:
1. A radar detection system for user-activated, non-contact activation of a powered closure member coupled to a vehicle body of a vehicle, comprising:
at least one radar sensor assembly including at least one transmit antenna for transmitting waves and at least one receive antenna for receiving the waves after reflection from an object in a detection zone and coupled to the vehicle body for sensing an object in the detection zone and outputting a sensor signal corresponding to the object in the detection zone based on the waves received by the at least one receive antenna; and
an electronic control unit coupled to said at least one radar sensor assembly to determine a speed and an amplitude using the sensor signal corresponding to the at least one of a motion and a position of an object relative to the at least one radar sensor assembly;
wherein said electronic control unit is adapted to analyze the speed and the amplitude to determine when the object is performing an activation gesture in the detection zone;
wherein said electronic control unit is configured to control movement of the closure member when the object is determined to be performing the activation gesture in the detection zone;
wherein said electronic control unit is configured to initiate movement of the powered closure member in response to the activation gesture corresponding to a valid activation gesture; and
wherein said electronic control unit is configured to characterize the motion of the object only using the speed and the amplitude.
