ADS-B information based transmitter localization in passive radar

Transmitters' locations are usually assumed to be known in passive radars that exploit the third-party radio sources as illuminators of opportunity to detect targets of interest. However, there are such cases where transmitters' locations are unavailable in advance, causing difficulties for target localization. To address the problem, this paper investigates a novel transmitter localization method that combines the decoded automatic dependent surveillance-broadcast (ADS-B) information and passive radar measurement information. The localization model is established at the first, followed by the discussion of localization uniqueness and accuracy. The feasibility of the proposed method is further verified by numerical analyses.
