Advances in Bistatic Radar updates and extends bistatic and
multistatic radar developments since the publication of Willis'
Bistatic Radar in 1991. New and recently declassified military
applications are documented, civil applications are detailed
including commercial and scientific systems and leading radar
engineers provide expertise to each of these applications. Advances
in Bistatic Radar consists of two major sections:
Bistatic/Multistatic Radar Systems and Bistatic Clutter and Signal
Processing. Starting with a history update, the first section
documents the early and now declassified military AN/FPS-23 Fluttar
DEW-Line Gap-filler, and high frequency (HF) bistatic radars
developed for missile attack warning. It then documents the
recently developed passive bistatic and multistatic radars
exploiting commercial broadcast transmitters for military and
civilian air surveillance. Next, the section documents scientific
bistatic radar systems for planetary exploration, which have
exploited data link transmitters over the last forty years;
ionospheric measurements, again exploiting commercial broadcast
transmitters; and 3-D wind field measurements using a bistatic
receiver hitchhiking off doppler weather radars. This last
application has been commercialized. The second section starts by
documenting the full, unclassified bistatic clutter scattering
coefficient data base, along with the theory and analysis
supporting its development. The section then details two major
clutter-related developments, spotlight bistatic synthetic aperture
radar (SAR), which can now generate high resolution images using
bistatic autofocus and related techniques; and adaptive moving
target indication (MTI), which allows cancellation of nonstationary
clutter generated by moving (i.e. airborne) platforms through the
use of bistatic space-time adaptive processing (STAP).
This is the only English language book on bistatic radar. It starts
with James Casper's fine chapter in the first edition of Skolnik's
Radar Handbook (1970), capturing previously unpublished work before
1970. It then summarizes and codifies subsequent bistatic radar
research and development, especially as catalogued in the special
December 1986 IEE journal. It defines and resolves many issues and
controversies plaguing bistatic radar, including predicted
performance, monostatic equivalence, bistatic radar cross section
and resolution, bistatic Doppler, hitchhiking, SAR, ECM/ECCM, and,
most importantly, the utility of bistatic radars. The text provides
a history of bistatic systems that points out to potential
designers, the applications that have worked and the dead-ends not
worth pursuing. The text reviews the basic concepts and
definitions, and explains the mathematical development of
relationships, such as geometry, Ovals of Cassini, dynamic range,
isorange and isodoppler contours, target doppler, and clutter
doppler spread.
