九十年代日本的有源相控阵雷达的TR模块的一点资料.

UNITED STATES IS EVALUATING
JAPANESE RADAR MODULES ALTHOUGH
POTENTIAL USES ARE UNCERTAIN
========================================================== Appendix II
The United States has obtained more information on the Japanese
active phased array fire control radar than any other non-derived
FS-X technology.  In August 1992, DOD purchased five Japanese FS-X
radar transmit/receive modules, supporting connectors, and technical
data for testing purposes.  DOD paid the then current Japan Defense
Agency/Mitsubishi Electric Corporation prototype module contract
price of $4,800 per unit and about $70,000 for technical data and
additional items required to test the modules.
Mitsubishi Electric officials reported in November 1993 that they had
reduced module unit costs to about $3,300.  Mitsubishi Electric
officials would like to reduce module costs even further by
increasing the module production run to at least 20,000 units
annually.  Mitsubishi Electric's cost goal is about $1,400 per unit
for the FS-X program, assuming production of 120,000 units (or enough
for about 130 aircraft).  Mitsubishi Electric officials noted that
they do not expect to reach the $1,400 per module goal until 2 years
into full-rate FS-X production.
Mitsubishi Electric officials said they will pursue commercial
applications for FS-X transmit/receive modules that could reduce
module costs during FS-X production.  Mitsubishi Electric officials
noted, however, that commercial applications are not practical at
this time because of the modules' high cost.  Commercial applications
could include air traffic control antennas, satellite and mobile
communications, and anticollision automobile radars.
In August 1993, U.S.  engineers at the Wright Laboratory Solid State
Electronics Directorate began testing the five radar modules DOD
purchased from Japan.  By February 1994, the United States had
finished a complete set of verification tests for module performance.
The tests indicated that the modules perform according to
specifications and will meet Japanese FS-X radar requirements.  A
U.S.  engineer involved in the testing said that the performance of
Japanese modules was very good and in one area are on a par with the
best U.S.  modules.
In May 1994, a U.S.  radar module testing team visited Japan to
compare and verify U.S.  and Japanese test results.  U.S.  engineers
may conduct additional tests to assess the performance of FS-X radar
modules relative to U.S.  modules planned for use on the F-22
aircraft.\1 DOD was preparing a report summarizing the results of the
radar testing at the time of our review.
--------------------
\1 Japan has also tested a complete FS-X radar array on the ground
and in flight aboard a specially modified Japanese C-1 electronics
testbed aircraft.  Japan had not shared its radar array testing data
with the United States as of March 1994, according to a radar expert,
nor would Japanese officials permit us to observe ground-based radar
array testing during our November 1993 trip to Japan.UNITED STATES IS EVALUATING
