There are provided a through-the-obstacle radar system and method of operating thereof comprising recording signals and/or derivatives thereof collected during a certain substantial monitoring period, and using the recorded information for generating patterns informative of a monitoring scene. There are further provided a method of motion detection based on through-the-obstacle radar and the system thereof. The method comprises collecting signals and/or derivatives thereof acquired by the radar system during a certain substantial monitoring period and accommodating respective records, said records comprising information characterizing the signals and/or derivatives thereof and information indicative, at least, of the time the signals were obtained; processing the accommodated records and generating at least one histogram characterizing a normative motion level at different time intervals; comparing an actual motion level with the level in the normative histogram corresponding to the same time intervals; and recording the motion as detected if its actual level fits a certain relationship with the corresponding level in the normative histogram. |
