To increase the capability of searching, detecting, classifying, and identifying contacts particularly at night and in poor weather, the Advanced Integrated Multi-sensor Surveillance (AIMS) system is being developed. The AIMS system is advanced through the integration of five sensors with active gated capability into a single gimbal. As such, the system will support a myriad of missions for both the CP-140 and Fixed Wing Search and Rescue (FWSAR) communities including timely search and rescue (SAR) response and ground surveillance in aid of the Land Forces (LF). To ensure optimal performance the AIMS system requires an appropriate interface and controls, the design of which must realize the interaction between technological capability and operator performance. This document, prepared by CAE Professional Services on behalf of Defence Research and Development Canada, presents preliminary design concepts and associated rationale for the AIMS Operator Machine Interface (OMI). The intent is to provide a framework for the future evolution of the AIMS OMI as well as identify areas for investigation.
