Systems and Methods for Detecting Physical Objects Using Passive Radar Receivers

A method of determining the location of a physical object using a passive radar receiver includes determining if a transmitter beam sweeping period (TBSP) is known, and executing a TBSP-based receiver beam sweeping if the TBSP is known. If the TBSP is not known, determining if the TBSP can be measur...

Zusammenfassung:	A method of determining the location of a physical object using a passive radar receiver includes determining if a transmitter beam sweeping period (TBSP) is known, and executing a TBSP-based receiver beam sweeping if the TBSP is known. If the TBSP is not known, determining if the TBSP can be measured, and executing the TBSP-based beam sweeping if the TBSP can be measured. The method includes executing a random receiver beam sweeping if the TBSP is not known and cannot be measured. The method includes determining a relative time of arrival of radio signals between the LoS path and the target path, and determining the propagation times on the LoS path and on the target path. The method includes determining the location of the physical object using the propagation times.
