Abstract : The Defense Research Establishment Ottawa has been involved in the development of several mission-specific airborne inertially based multi-sensor integrated avionics systems. More specifically, DREO has successfully completed the Phase II development and flight trial evaluation of an airborne Synthetic Aperture Radar Motion Compensation System (SARMCS). To achieve high resolution, high contrast and low geometric distortion in synthetic aperture radar imagery, it is necessary to apply accurate motion compensation to the radar returns. The hardware configuration consists of a ring laser gyro inertial navigation system, a doppler radar, a baroaltimeter and a specially designed strapped-down Motion Compensation Inertial Measurement Subsystem (MCIMS). the Department of National Defense is also undertaking a program to develop and flight test a Helicopter Integrated Navigation System (HINS) which can satisfy the operational requirements of Canadian New Shipborne Aircraft (NSA). The roles of this maritime helicopter include search and rescue, Anti-Surface Surveillance and Targeting (ASST), Anti-Submarine Warfare (ASW), and Anti-Ship Missile Defense (ASMD). This lecture will describe the development of appropriate Kalman filters to integrate the selected avionics configurations. Design objectives, configuration definition, simulation analysis and some flight test data are presented.
