ABSTRACT:
Actual correlation data is stored at38A. Such actual correlation data is data representation(s) of correlation(s) between or among distance(s) to object(s) intended to be detected and phase difference(s) of respective reflected wave(s) established with due consideration having been given to reflection of microwave(s) by object(s) (ceiling surface(s), wall surface(s), floor surface(s), etc.) other than object(s) intended to be detected which may be present within area(s) intended to be protected. Distance(s) to object(s) intended to be detected is or are measured, based on such actual correlation data, from phase difference(s) of respective reflected wave(s) that has or have been detected.
