Multistatic target tracking for passive radar in a DAB/DVB network: initiation

A passive radar system that coopts digital broadcast (DAB/ DVB) signals is appealing but challenging: a single-antenna receiver system can only measure a bistatic range/range-rate; and, due to the energy-efficient multitransmitter commercial implementation, there is a confounding uncertainty as to which transmitter (illuminator) was responsible for a given “hit.” In a companion paper we proposed some ways to track directly in native geographic coordinates. Here we suggest and compare two approaches for track initiation.
