Abstract : The report concerns the reduction of shipboard radio interference between strong transmitted signals and weak received signals. Fundamentally, there are only three modes of isolation for radiating devices; time, frequency, and space; that is, the antennas may be operated on a time-share basis so that during reception of a weak signal all transmitters are quiet; or, filters may be used in each antenna channel to sift out unwanted signals (this includes such techniques as servo-controlled phase cancellation); or, the antennas may be oriented so that coupling among them is minimized (this includes antenna polarization orientations).
