Greetings SIGCIS,<br>
The SAGE air defense system in the US, built in the late 1950's,
is well known among Cold War historians-of-technology.<br>
But there was a competition prior to the awarding of the contract
that became SAGE, to Lincoln Labs and IBM.<br>
The competing system was "Air Defense Information System", developed
at the University of Michigan's Willow Run Laboratory, in the early
1950's. That, in turn, was based on a system developed in the U.K.,
by Elliott Automation, for naval air defense, as outlined in Simon
Lavginton's excellent book, "Moving Targets".<br>
I know the ADIS system was very different from MIT / Lincoln Labs'
digital-computer proposal, but, other than being based on analog
techniques, I know little about how ADIS works, and have not found a
repository of technical reports.<br>
Is there anyone on this list who might have run into ADIS
previously, and might be able to suggest where to search for a
description of the ADIS technical approach?<br>
<br>
Thanks<br>
