multiple signals and functions, such as
EW, communications and signals intelligence (SIGINT) with "a limited number
of power amplifiers and apertures." The
front-end should provide an adjacent
channel STAR capability that allows for
the operation of a large number of wideband (500 MHz) and narrowband (<50
MHz) RF functions, and provide up to
120 dB of isolation in adjacent transmit
and receive (TX/RX) channels.
A third mmW EW demonstrator should
be able to detect signals and automatically deceive or deny the operation of
the emitting system(s) over the 18- to
45-GHz frequency range. The transmitter
subsystem should be capable of 1-4 kW
or greater effective radiated power (ERP)
for small decoy applications or capable
of being combined to achieve 100 kW or
greater ERP for large platform applications. It should also be capable of automatic signal processing and generation
of EW attack waveforms and techniques.
The overall goal of the compact and
efficient EW antennas area is to improve
the capability of EW systems to detect,
deny or deceive sensors, communica-

tions or other systems using physically
small antennas covering HF and VHF
(3-300 MHz) frequencies. Conformal designs are desirable with no physical dimension exceeding 1 meter (threshold)
or 30 centimeters (objective). Designs
should achieve a voltage standing wave
ratio (VSWR) of better than 3:1 (threshold) or 2:1 (objective) while maximizing
efficiency and gain over the full 3- to
300-MHz band. Electronic attack (EA)
antenna designs should demonstrate
sustained power handling capability of
greater than 100 W (threshold) or 1 kilowatt (objective) is desired. For electronic
support (ES) antenna designs, the ability to precisely determine the direction
of the detected signal is desired, as well
as the ability to precisely geo-locate the
signal when information from multiple
antennas are networked together.
The W-Band mmW high-power transmitters area targets sensors or weapons
guidance systems operating in the mmW
frequency range. The current solicitation is limited to the W-Band (75-110
GHz) range. Transmitter systems (consisting of power amplifier(s), matching

network, and radiating element) should
be capable of achieving 1-4 kW or greater ERP for small decoy applications or
capable of being combined to achieve
100 kW or greater ERP for large platform
applications. Technology solutions can
use either vacuum or solid-state components or combinations. The system
should be able to project the ERP across
the full 75- to 110-GHz band against a
far-field target in a controlled and sustained beam and be able to transmit
linear and phase controlled jamming
waveforms capable of preserving complex signal content and coding.
The final innovative EW concepts area
is looking for "truly innovative concepts
which could fundamentally change the
way military forces conduct EW operations." Proposals in this area should focus on innovative solutions involving
emerging, cutting-edge technologies, as
solutions using commercial off-the-shelf
(COTS) or other traditional technologies
will be less desirable, unless the application of the technologies is truly innovative in approach. Also, proposals that
require government-furnished equip-
