Abstract
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.
