Closed-form estimators for multi-pulse TDOA localization

Most time difference of arrival (TDOA) localization algorithms process only one set of TDOA measurements to compute the emitter location. In certain applications such as pulse radar localization we are presented with a large number of TDOA measurements over very short time intervals. The paper develops new closed-form multi-pulse localization algorithms that exploit additional information available from multiple TDOA measurements. Reduced bias estimators are also developed. The superior bias performance of the new algorithms is demonstrated by way of computer simulations.
