Estimation of Transmitter Position Based on Known Target Trajectory in Passive Radar

The paper deals with the problem of estimating the unknown transmitter position in passive radar. It is assumed that the radar is using an illuminator of opportunity, whose position is not known, but the bistatic measurements of a target or targets are obtained. If the Cartesian trajectories of those targets are known, e.g. from GPS or ADS-B, the transmitter position can be found by matching converted trajectories into the bistatic domain.
