Query: Cross Correlation-based Direct Positioning for Wideband Sources using
  Phased Arrays   Recent developments in Phased Array direct positioning methods have improved
accuracy for passively geo-locating multiple radio frequency-emitting signal
sources. However, the number of geo-localisable signal sources is still limited
by the number of antenna elements at each node. This is the limitation for
methods based on MUSIC, otherwise known as signal subspace identification. This
paper attempts to exploit properties of wideband signal sources to
compartmentalise signals into their respective Time Differences of Arrival. By
performing direct positioning after the compartmentalisation process, we will
show that geolocation of a large number of sources can be achieved by our
proposed method at accuracies that exceed all existing methods, especially
under low signal-to-noise ratio conditions.
