JED - October 2014 - 48

This growing threat spurred a range
of efforts to improve anti-ship countermeasures. Chaff systems were modernized to incorporate larger RF payloads,
improved fire-control algorithms, and
greater levels of automation. For countermeasures against these threats,
rapid self-erecting corner reflector devices were introduced on a limited scale,
and even helicopters were pressed into
service with off-board "home-on-jam"
decoys hanging below them. Work commenced on software-driven EW com-

mand and control modules intended to
better coordinate soft-kill responses.
Development began on a new generation
of expendable active off-board decoys
designed to seduce even the most advanced seekers, and early thought was
given to the use of long-endurance unmanned air vehicles (UAVs) to carry or
seed countermeasures payloads.
In the three decades since the
1980s, the technology and techniques
embodied in anti-ship RF seekers has
become more advanced and more di-

verse, as the leading European, Russian and Chinese manufacturers have
sought to engineer terminal guidance
packages that are more discriminative and less susceptible to electronic
countermeasures. Also, while seekers
operating in the J band of the electromagnetic spectrum have traditionally
been preferred because of their robust,
all-weather performance in the maritime environment, Ka-band millimeterwave (mmW) radar seekers associated
with a new breed of Chinese anti-ship
missiles have already proliferated into
the Persian Gulf region.
Yet, the science of shipborne soft-kill
does not appear to have come all that
far over the same period. Active RF decoys, such as "Siren" and "Nulka," have
entered service with only a handful of
navies, and UAVs have yet to figure on
the front-line in a soft-kill capacity. The
vast majority of surface warships still
rely on chaff, typically fired from fixed
(rather than trainable) launchers, as
their principal RF countermeasure.
This perception belies the truth to
some degree. There have been advances,
but developments have tended to be
relatively modest and incremental in
nature. Many pertain to improved algorithmic techniques inboard (designed
to compute optimized decoy placement
patterns and course-to-steer advice)
rather than improvements to countermeasures mechanisms themselves.
Trainable launchers have also started to
feature in some more advanced navies.
What should also be pointed out is
that work is ongoing in the defense scientific community and across industry
to raise the maturity of new technologies and system concepts likely to reach
fruition by the end of the decade. Some
of these projects revive long established
soft-kill concepts, albeit in a much modernized form. Equally, it is clear that
some "legacy" RF countermeasures will
continue to have a significant role for
some time to come.

corner reflector devices can be traced
