We consider passive surveillance using time and frequency difference of arrival signals received by mobile receiver pairs. Signals received by a pair of receivers are correlated in time and frequency, followed by a detection process. In addition to the target (emitter) measurements, we may also create a number of spurious detections in each scan. This paper considers local (distributed) tracking using...
This paper presents an effective recursive tracking method for the single mobile emitter using correlated TDOA measurements. In multiple-sensor environment the time difference of arrival (TDOA) measurements are correlated. We consider only the case of single emitter tracking without data association issues, e.g., no missed detection or false measurements. We describe a scenario of three static receivers...
