Friday, September 19, 1986 THE DETROIT JEWISH NEWS
over the Bekaa Valley on June 9, 1982,
perhaps as many as 100 aircraft joined
battle simultaneously. The close proximi-
ty of the opposing aircraft resulted in a
surprisingly high number of cannon kills.
Of the LaVi's home-grown components,
none is more important than the radar, for
searching, tracking, and target identifica-
tion. It's the plane's "dominant sensor or
avionic box," according to Bernknopf.
This wasn't always the case. Until the
1970s, fighter radar was beset by two ma-
jor problems. The first was bulk. The se-
cond was that an airborne radar couldn't
look down discriminatingly; the earth sent
up its own reflective electronic "clutter"
that swallowed the blip of an aircraft at a
lower altitude, to say nothing of that of a
tank or other moving target on the
ground.
But by mid-1970s these shortcomings
were largely eliminated. The steps toward
shrinking the radar have been the same as
those in other electronic systems. The
look-down difficulties have been overcome
with circuitry that measures the change in
perceived frequency of signals from a mov-
ing target.
The Lavi's radar can also map the
ground to show roads, rivers, buildings,
vehicles and such structures as radar or
missile emplacements. The radar won't
have quite the range of the somewhat big-
ger unit in the F-16 or the substantially
larger radar of the F-15, but its builders
insist that its all-important signal-pro-
cessing ability will be second to none.
The Lavi's designers are aware that a
pilot could be overwhelmed by information
from all the on-board computers. So the
decision was made to keep_the Lavi's dis-
plays strikingly simple. Gone are the
endless arrays of dials and switches that
surround the pilot of even a small plane.
In their place are three television-like
cathode-ray tubes (CRTs), and, projected
onto clear plexiglass just in front of the
cockpit window, a holographic "heads-up
display," or HUD.
Most of what the pilot needs to know
will appear on the CRTs or the HUD. One
screen will provide a battle picture in as
many as seven colors. It might show
enemy aircraft in red, for example, friend-
lies in blue, unknowns in yellow, missile
sightings in orange. The display can also
demarcate safe and dangerous flight cor-
ridors. The Elbit official calls it a "big
video game." One of the hardest chal-
lenges for Elbit's electronic engineers, he
says, has been to get colors of unparalleled
brightness. Anything less would disappear
as the brilliant sunlight of the upper air hit
the displays.
Israel's first prime minister, David Ben-
Gurion, foresaw the crucial role of air
power in Israel's security — long before
the capabilities of its air force matched his
vision. "He understood that our standing
army would always be tiny," says Blum-
