A portable many-element coherent receiver system for passive radar and
space domain awareness
Abstract
We describe a portable 32-antenna coherent passive radar system. The
system was developed with space domain awareness in mind, but can be
used for aircraft and nearer objects. We describe the physical and
signal processing architecture and the results of a system test using
VHF-band broadcast transmitters as illuminators. Using a combination of
phased-array beamforming and delay/Doppler tracking, the flight path of
a small training aircraft was tracked with high accuracy in excellent
agreement with public flightpath data.
