Abstract：In the context of the space-based passive cooperative multi-target angular data association and initial orbit determinationmission，toaddressthe problemof poor orbit determination accuracydue to the high association mis-match rateof the traditional method in the complex environment where sensor clutterand missed detection are taken into account，a method for multi-target data association and multi-target initial orbit determination based on parameter correction and clustering estimation is proposed.First，a dynamics model incorporating the Earth’s non-spherical J2 term and the Moon’s gravitational perturbation and line-of-sight anglemeasurement modelare developed，asensor clutterand missed detection modelisderivedandasimulated data generator is constructed. Second，thedata association cost matrixis constructed according to the evaluation metrics of the measurement association，the cost matrix processing method based on parameter corction and clustering estimation is proposed，and theoptimal alocationalgorithmisapplied to findout theassociation results.Third，the global associations are derived based on the cooperative asociations and the time-series associations，and the multi-target orbit velocities are solved with reference to theglobal associations.Finally， the proposed method is validated by numerical targeting simulation experiments with coordinated observation of 10 targets in the geostationary Earth orbit neighborhood.Simulation results show thatthe proposed method is effective in resisting the influence of sensor clutter and missed detection，improving theassociation and multitarget initial orbit determination accuracy，and the relative orbit error is less than 1% ：
