[Milsurplus] Spoof countermeasure against Japarception of proximtyity fuze signals

[Jack Sullivan]

  My original question on this topic did not relate to the jammingof these projectiles - it had been shown that a modified APT-4 in a B-17 wouldcause premature  detonation of theseshells as observed from the aircraft. My question related to U.S. concern thatthe Japanese could pick up the signals radiated by the shells & develop inturn their own jammer or other countermeasure. I’ve read that in order tocounter this & to confuse potential Japanese eavesdropping, U.S. Navy shipstransmitted a number of ‘spoof’ signals in order to confuse them. This isobviously quite a different topic than jamming. I’m looking for any informationrelating to U.S. spoof transmissions & associated equipment used atOkinawa.Jack
