This document describes the operating concept of the Northern Watch Technology Demonstration Project Underwater Sensor System. The proposed operating concept is a description of the actual sensor system, a scenario under which the sensors are expected to work, a description of the signal processing requirements, an initial look at the requirements of sensor integration with other Northern Watch sensors, and the bandwidth requirement to support unmanned operations – all of which are subject to the requirement of an unclassified mode of operation. It is shown that constraints on the available communication bandwidth lead to a requirement for a certain degree of data processing that would allow for useful operations when it is impossible to transmit the raw data of the sensor system. The on-site data processing results in an elevated degree of potential information classification that must be managed in order to allow for unmanned operation. The size of data products and the ability to transmit these products to a southern operator station is discussed. Target Detection Messages are identified as the primary data product of the array system. The rate of message production is discussed and a medium to high risk software development is proposed that will compress the message information to a degree that allows continuous transmission. Expert advice will be required to ascertain that the proposed concepts will be found in compliance with security guidelines.
