F-15的电子扫描相控阵雷达
波音公司已对美国空军和空中国民警卫队的F-15C/D战斗机实施改进升级,为其换装雷
神公司研制的APG-63(V)3有源相控阵雷达(AESA)。
APG-63(V)3雷达使用了现役APG-63(V)2雷达的软件和APG-79雷达(用于F/A-18E/F
“超级大黄蜂”战斗机上)的发射/接收组件,具有高性能、高可靠性和经济性好等特
点。

The Captor-E will feature an innovative “re-positioner” with two rotating
joints so that the array can cover a wide field of regard (WFoR).
electronic scan angle + pointable gimbal-mounted mechanical scan angle =
wider angle of view vis-a-vis fixed AESA
"AESA And Typhoon
Posted by Bill Sweetman at 2/19/2009 10:24 AM CST
Everyone buying fighters wants an active electronically scanned array (AESA)
these days, no doubt after reading Dave "Mr AESA" Fulghum on the subject.
But Eurofighter remains wary about the issue. The consortium's executives
still stay that - for today - the mechanically scanned (M-Scan) Selex Captor
beats any in-service AESA for the Typhoon's mission, even though Selex
itself is ready to go with its Vixen range of AESA radars. A clue as to why
they think that way emerged at the Aero-India seminar last week.
Discussing future technologies, Dr, Peter Gutsmiedl, senior vp engineering
at EADS Military Air Systems, pointed out ways in which AESA could be
integrated into Typhoon - one being the conventional fixed, canted antenna.
They included an antenna with auxiliary side arrays, an azimuth gimbal and
the so-called "swashplate" radar, a canted antenna on a rotating mount:
What's behind this thinking? A few years ago, Prof. John Roulston - former
technical director at BAE Systems' radar division, now part of Selex -
presented a paper in which he pointed out a limitation of AESA: at extreme
scan angles the effective aperture decreases, and the performance of the
radar (range, sensitivity and jamming resistance) declines as a result. So
today's M-Scan has a larger field of regard than a fixed AESA, and better
performance at the edge of the scan envelope.
This is important for Typhoon because the whole system - in the air-to-air
regime - is influenced by air-combat simulations in which a fighter-to-
fighter engagement could involve multiple MRAAM shots, followed by a
supersonic turn to evade the adversary's fire and extend the F-pole - the
distance between the launch aircraft and the target at impact. To do this,
it's essential to have a radar that can continue to track the target and
guide the missile as the shooter turns away.
The gimbal of a pointable AESA does not have to be anything like as fast as
an M-Scan gimbal. The high-speed stuff, tracking a moving target, is still
done electronically, with the gimbal moving relatively slowly to optimize
the field of view.
Moreover, the electronic field of view is now added to the gimbal scan: the
swashplate design shown here adds the 60-degree AESA limit to its 45-degree
cant angle, to cover 105 degrees in all directions - a total 210-degree
field around the nose.
By the way, the designers of the Su-35 think the same way, and the F-22 has
space, weight and cooling provision for side arrays, but so far they have
been deferred due to budget cuts. "
