Abstract
The device (3) has a transmitting module (8) emitting chirp pulses (21) and fixed-frequency pulses (22) in a predetermined transmit sequence, where the pulses are alternately enterable. Two separated evaluation electronics (16, 17) evaluate chirp reception signals (23, 24) that are received by a receiving module (11) at specific pulse such that the evaluation electronics generate separate pulse-specific evaluation signals. The evaluation signals are partially comparable by information contents such that a velocity information signal is determinable as the evaluation signals. An independent claim is also included for a method for detecting an object using a radar device.
