You try walking around on the flight deck on a ship with a "mag loop" talking headset on! If you can count fast enough, you not only clearly get the scan rate of the ships radar, but its PRF as well!
Worked in an AEW radar workshop for a while. Big bits of kit them. Hook it up to a dummy load, insert pies in waveguide, Tx for 3 - 4 sec, red hot pies ready for lunch!
Only snag, get distracted at the critical moment - Tx for 5+ sec and the cry of "Who's burnt the ******* pies?" went up!!!! Oh, and whatever you do, do take 'em out the tin foil before you try this one at home folks!!!!
For info, this technique worked on any pie - not just chicken! Never did try a full Sunday roast tho!
