SYSTEM AND METHOD FOR CALIBRATION OF MEASUREMENTS OF INTERACTED EM SIGNALS IN REAL TIME
First Claim
1. A method of calibrating a measurement of electromagnetic (EM) signals, comprising:
- a) separating at least one reference signal component from an EM signal;
b) delaying at least one of said EM signal and said at least one reference signal component;
c) extracting said EM signal after an interaction with a target object and said at least one reference signal component after at least one interaction with at least one reference element from different time slots in a reception; and
d) calibrating a measurement of said interacted EM signal by a signal analysis of said extracted and interacted at least one reference signal component.

Abstract
A method of calibrating a measurement of electromagnetic (EM) signals. The method comprises separating at least one reference signal component from an EM signal, delaying at least one of the EM signal and the at least one reference signal component, extracting the EM signal after an interaction with a target object and the at least one reference signal component after at least one interaction with at least one reference element from different time slots in a reception, and calibrating a measurement of the interacted EM signal by a signal analysis of the extracted and interacted at least one reference signal component.

21. A monitoring apparatus of performing a measurement of electromagnetic (EM) signals, comprising:
-
a transmitter which generates an EM signal which is directed toward a target object; a receiver which intercepts said EM signal after an interaction with said target object; a measuring unit which performs a measurement of a property of said target object according to said interacted EM signal; and a calibration module which separates at least one reference signal component from said EM signal and computes a calibration for said measurement; wherein said EM signal and said at least one reference signal component are not diverted by a switch.
