Abstract: Generally discussed herein are systems and apparatuses that are configured to and techniques for matching track fragments. According to an example, a technique can include receiving data indicating a first and second actual ToA of first and second SIGINT signals at a collector, estimating first and second sets of estimated ToAs of the first and second SIGINT signals at a collector, respectively, each of the first and second sets of estimated ToAs based on a different track fragment of a first plurality of track fragments active at the first time and a different track fragment of a second plurality of track fragments active at the second time, respectively, or matching a track fragment of the first plurality of track fragments with a track fragment of the second plurality of track fragments based on the first and second sets of estimated ToAs and the first and second actual ToAs.

Abstract: Methods and apparatus for phased-based pre-carrier signal detection in a communication system are described. In embodiments, inphase and quadrature (IQ) data is generated from a received signal. A current phase delta value is determined from the IQ data and combined with existing phase delta value, such as an averaged phase delta value, which is compared with a threshold value to determine if a pre-carrier signal in the received signal has ended.
