INSPIRED RESEARCH	PRESS RELEASE IR/1	2008-07-17

FOR IMMEDIATE RELEASE:

Inspired Research, New York, (IR) reports a remarkable discovery
expected to revolutionize navigation, imaging and communication
technologies. IR demonstrates that applying an exponential chirp
transform to actual RF or IF waveforms in a receiver will shift the
spectral content corresponding to each source in proportion to its
distance from the receiver, like the Hubble redshifts in astronomy,
because of a basic relation of the phase of a received wave to its
frequency and total path delay. The signal of a specific source can
be then isolated by a simple filter. Chirp transforms have been used
in radar and medical imaging for years, but always in chirp-dechirp
pairs, so that this remarkable property was never exposed.

IR's discovery makes it possible to select a source by range
independently of signal content or modulation, similar to how a
phased array antenna can isolate a source by its direction. A
peer-reviewed paper and poster will be presented at the prestigious
SPIE Optics+Photonics Symposium in San Diego on August 11th, in the
Nature of Light II: Light in Nature special event. Discussions are
under way for empirical validations at both radio and optical
wavelengths, and acoustic tests are being explored.

If validated, the discovery would mean an immediate end to the FCC
frequency allocations and to spectrum auctions worldwide, as the
technique would enable users of radio, cellphone and other receivers
to select their stations or signal sources by range, even when their
signals overlap in frequency and spread-spectrum code. GPS receivers
would not need to decode the time signals, police and rescue forces
would be able to instantly locate emergency beacons without
triangulation, communication satellites would become unjammable, and
bandwidths would be effectively multiplied overnight, as already
proposed in IEEE WCNC and MILCOM (2005) papers. Transforming LED
light into terahertz (THz) or pocket x-ray diagnostics devices might
become feasible as well, with the physical implementations of the
chirp disclosed in IR's worldwide patents portfolio.
