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.

1. A method of calibrating a measurement of electromagnetic (EM) signals, comprising: conducting an EM signal to a splitter via a dynamic transmission path having variation in at least one of a time response and a frequency response over time;separating at least one reference signal component from said EM signal using said splitter;delaying at least one of said EM signal and said at least one reference signal component;intercepting a reception that combines 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 having at least one of a known time response and a known frequency response;extracting said EM signal after said interaction with said target object and said at least one reference signal component from said reception during different time slots; andcompensating for said variation by calibrating a measurement of said interacted EM signal by a signal analysis of said extracted and interacted at least one reference signal component. 2. The method of claim 1, wherein said method is performed while measuring said EM signal for an analysis of at least one property of said target object. 3.
