Paper Abstract

We present an Integrated Multisensor Synthetic Imaging System (IMSIS) developed for low-visibility, low-level operations, tailored to Army rotorcraft. IMSIS optimally avails itself of a variety of image-information sources: FLIR, mm-Wave RADAR and synthetic imagery are all presented to the flying crew in real time, on a fused display. Synthetic imagery is validated in real time by a 3D terrain sensing radar, to ensure that the a priori stored database is valid, and to eliminate any possible aircraft positioning errors with respect to the database. Extensive human factor evaluations were performed on the fused display concept. All pilots agreed that IMSIS would be a valuable asset in reduced visibility conditions and that the validated SVS display was rated nearly as flyable as a good FLIR display. The pilots also indicated that the ability to select and fuse terrain information sources was an important feature. IMSIS increases situational awareness at night and in all weather conditions, while considerably reducing pilot workload compared to separately monitoring each sensor and enhancing low-level flight safety by updating the terrain in real time. While specifically designed for helicopter low-level flight and navigation, it can aid hover and touchdown and landing for both fixed and rotary wing platforms as well as aid navigation even in non-airborne domains.
