This thesis was conducted as part of the efforts related to WPI's Precision Personnel Location (PPL) project, the purpose of which is to locate emergency personnel in hazardous indoor environments using radio location techniques. A unique signal processing algorithm, sART, developed within the PPL project provides means to determine precise position estimates of a wideband transmitter from multipath corrupted signals captured by distributed receivers. This algorithm has synchronization requirements that can not be met without extraordinary expense and complexity by direct means. This thesis develops digital signal processing that achieves the necessary synchronization to satisfy the sART algorithm requirements without additional implementation complexity. The mathematical underpinnings of this solution are introduced and the results are evaluated in the context of experimental data.
