New phenomena which provide target direction-of-motion detection with millimetre-wave Doppler sensors are described. The phase relationships between the Doppler ‘beat’ fundamental frequency and harmonics can be such that a natural nonsinusoidal waveform effectively ‘tilts’ in opposite directions for opposite target motions. Criteria for practical applications of these phenomena are analysed. Hardware and signal processing circuitry are described for radars utilising these phenomena.
