1. A system for detecting position of a target transmitter, comprising:

  • two or more time-difference-of-arrival (TDOA) units, each TDOA unit including two or more receivers that are synchronized together within the TDOA unit to obtain one or more TDOA measurements, but wherein each TDOA unit operates asynchronously with respect to the other TDOA units; and

    a centralized data processing unit that receives the TDOA measurements or TDOA information calculated based on the TDOA measurements from the two or more TDOA units in order to estimate a position of the target transmitter.
