Identification of Air Targets by using Secondary Application of Terrestrial TV

Numbers of bistatic radar systems based on non-cooperative TV transmitter are known currently. These systems provide air target detection and tracking but none of them have target identification ability. It is proposed in the paper a technique of air target identification based on the system transfer function parameters estimation. Modern terrestrial TV stations in Europe are operating mainly in UHF band with channels spacing not less than 20MHz. Using, as an example, 4 channel transmitter operating at 480 -540 MHz, the singularity expansion method is introduced. The technique based on the signatures of resonance models is suggested. These signatures are robust to range and aspect angle of targets and the method could be applied in practice.
