Bistatic (Multistatic) Radar Using Television or FM Broadcast

Bistatic (multistatic) radar using television or FM broadcast is a kind of radar which employs a television or FM broadcast transmitter as the illuminator. Some advantages are obtained from this radar, such as anti-elint, electronic counter-countermeasure, detection of stealth targets and counter anti-radiation missile. This radar will be used in military area. The developing hisory and present situation of bistatic (multistatic) radar using television or FM broadcast is introduced in this paper. The principle of this radar is analysed and a receiver system block diagram is given. Basic measured parameters are time difference of arrival between the signal of a target and the signal from a transmitter, direction of arrival and Doppler frequency of a target. In addition, some key technologies for this radar are discussed. The synchronisation between transmitter and receiver in respect of antenna beams and time, the direction of arrival of a target, the signal processing in the receiver and the locating and tracking method for targets are included in the discussion.
