Multisource Localization from Delay and Doppler Measurements.

Abstract

The estimation of the locations of multiple radiating sources by analysis of passive array measurements is discussed. Computationally efficient, accurate source location estimators are derived based on differential delay and doppler measurements. The measurement of differential delay and doppler is also discussed; and, finally, the optimal tracking of moving sources via dynamic programming methods operating on correlogram and dopplergram data is presented. Keywords include: Localization, Tracking, Source location estimation, TDOA (Time-difference-of-Arrival), Time Delay, RD (Range Difference), Doppler, Spectral Estimation, and Closed-form Estimators.
