This document describes an initial assessment of the Rutter 100S6 marine radar system’s ability to perform a useful function as a limited air surveillance asset at a remote test site on Devon Island, overlooking Barrow Strait and Lancaster Sound. As part of the assessment, a set of trials was performed in the Ottawa-Gatineau area to measure the radar system’s ability to detect and track aircraft of opportunity in a land-based setting. The aircraft were of various types and sizes ranging from small general aviation aircraft (fixed and rotary wing) to large commercial jet airliners. Ground-truth of the aircraft classification, identification and course information was provided by a combination of visual means (i.e. naked eye, binoculars, and camera imagery) and, when available, Automatic Dependent Surveillance-Broadcast (ADS-B) reports. Only a few days of actual data collection was accomplished, which was performed intermittently over the period from 29 July to 19 September 2010. The outcome of the assessment was that this radar system has the potential to provide a useful, though limited, air surveillance role as long as the system constraints are respected. It was also determined that a more capable tracker would be needed if automatic surveillance of aircraft, with minimal analyst intervention, is required. The current alpha-beta tracker provided with radar system has difficulty initiating a track or maintaining track continuity on high speed (over 100 kph) manoeuvring t
