REDUCTION OF SHIPBOARD RADIO INTERFERENCE.

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).
