Successive-MFCW modulation for ultra-fast narrowband radar

摘要

Determining a speed and a range of an object by generating at least a first, second, and third interval-specific tone phase signals associated with at least three successive time intervals, wherein at least two of the generated and transmitted tones are different frequencies; determining at least a first, second and third interval-specific average phase value from the respective interval-specific tone phase signals; and then determining a range estimate of the object and determining a speed estimate of the object using at least two phase differences between the at least first, second and third interval-specific average phase values.

1. A method of determining a speed and a range of an object comprising:
generating at least a first, second, and third interval-specific tone phase signal by, during each of at least three successive time intervals:
(i) generating and transmitting a tone towards an object during a respective time interval;(ii) receiving an echo signal from the object during the respective time interval;(iii) demodulating the respective echo signal using the generated tone to generate an interval-specific tone phase signal; wherein at least two of the generated and transmitted tones are different frequencies; determining at least a first, second and third interval-specific average phase value from the respective interval-specific tone phase signals; determining a range estimate of the object and determining a speed estimate of the object using at least two phase differences between the at least first, second and third interval-specific average phase values.
