I can't even listen to shortwave much anymore because of all the EMI in town !

There have been survey instruments in that band before notably T151 at Cambridge which used the baseline of the Ryle 5km telescope:

Don't get your hopes up. The best chance is relatively nearby stars in our own galaxy - might just have enough signal to noise then if we catch them between inventing the thermionic valve and discovering spread spectrum transmission (which looks like noise anyway).

Seems like one could make a PPI display, using a nearby airport radar transmitter and your own receiver.

Been around for ages:

So much *said* in the abstract that I fear the worst for the rest. What an awful piece of prose!

DTIC reports have a wide range. A few are very good. Typically the best are somebody's PhD thesis.
