and signal processing, so it is essential that radar development is
accompanied by comprehensive experimental programs to measure
and archive all relevant material and environmental parameters
Biologically-Inspired Processing: Finally, a study of how processing in natural systems such as bats and dolphins has benefitted
from optimization through millions of years of evolution can teach
us some valuable lessons. The acoustic signals that some species of
bat use to identify, track, and intercept their prey are sophisticated,
and make use of intelligent, cognitive processing [6]. Different species of bat inhabit different environments and feed on different prey,
and the waveforms reflect this diversity; some are long, CW-type
waveforms, some are shorter and impulsive, and some even include
harmonics. In some species the frequency of the emission is adaptively lowered as it moves forward, so that the Doppler-shifted echo
from the target scene is still at the peak of the frequency response
of the bat's ear [7]. Even more impressive is the way in which the
waveforms are adaptively varied through the different phases of the
pursuit of insect prey, and evaluation of the ambiguity functions at
each stage show the difference in information acquired [8]. One
species of bat (Noctilio leporinus) feeds on fish, which it detects
using echolocation of the perturbation of the water surface caused
by the fish under the surface. Are there clues here that might help
us with radar detection of submerged objects such as submarines ?
a repeat interval one year is certainly too frequent, but two or three
years seems about right.
ACKNOWLEDGEMENTS
We express our thanks to ONR(G), AFOSR, and the Australian
High Commission for their support of this event, and all of the
participants, especially the session chairs and presenters (on whose
abstracts these summaries are based) and the poster authors.

CONCLUSIONS
So what did we learn? Firstly, that this is a really useful meeting
format, which should be more widely applicable. It depends on
being able to bring together the right people and encouraging them
to express their opinions in an honest and unfettered way. It is important that the participants understand that the purpose is to look
forward rather than back. Secondly, that it is important to be able
to capture the discussion in a form that is usable and useful - and
this article forms part of that, of course. Thirdly, that academia, industry, and government labs each have their own perspectives and
priorities, and to make genuine progress it is necessary to harness
all three in the right way. Fourthly, that there is strong support to
repeat the event. Opinion is divided on the appropriate timescale:
