Multistatic passive radars localize targets by using multiple bistatic range measurements. Multistatic localization requires all range measurements to be unbiased. It is proved by real data processing that registration is an important topic to be addressed. Traditionally, atomic clocks or GPS are used to achieve unbiased measurements. However, these approaches are unattainable under the case of multistatic passive radars as the transmitters of opportunity are beyond control. This paper proposes a novel registration method using noncooperative targets. The global convergence and accuracy of the proposed algorithm are obtained analytically. Computer simulations and experimental data are used to verify that the proposed algorithm possesses a good global convergence behavior and the performance can approach the Craḿer-Rao bound (CRB).
