Performance analysis and location methods in passive radars in air defense applications

Inactive radars do not have a transmitter and can use different signal sources. These sources include AM and FM radio, digital and analog television, cell phone signals, satellite signals, and more. Using each of these resources has its own advantages and disadvantages. Among the recent signals, digital TV signal (DVBT) and FM radio have major advantages and have received more attention. This paper examines how to systematically calculate and locate targets on a passive radar using television signals. Also, the extraction of the dynamic range of this radar is studied and some requirements in this regard are examined.
