Shipboard Wireless Intercommunication System: Radiax System Design and Test Plan.
Abstract
The approach analyzed here and in the subsequent shipboard evaluation in providing the ship with emergency communication between closed compartments is the utilization of a two-way radio (transceiver) system propagating low power RF energy through leaky or radiating tramsmission lines routed through-out the ship (or selected compartments), thereby creating an effective 'free space' for those areas served while containing the transmission within the ship. It is important to recognize that the low power of this system and shielding of normal ships cables will not provide any detectable interference to other ship systems such as weapons, navigation, etc. This lack of interference to normal ship power and control circuits operating at DC, 400 Hz or 60 Hz power, results mainly from the extreme frequency separation between the communication system operating at about 140 MHz and the other low frequency ship systems.
