Topic N92-159 stated a NAVAIR requirement for environmental degradation models to enhance the effectiveness of PC-based training devices. The purpose of this Phase I SBIR effort is to demonstrate feasibility of upgrading NAVAIR training devices with environmental degradation models using real world infrared video of target and background scenes. Phase I objectives will seek to (1) identify efficient PC-based degradation algorithms for environmental modelling (2) investigate real scene database and computer processing requirements for simulating infrared weapon performance in varying environmental conditions, (3) determine architectures for upgrading NAVAIR training devices for infrared Maverick and SLAM with environmental degradation modules. Multimedia technologies will be considered to optimize PC configuration for video storage, image processing, dynamic simulating and graphic realism. PC-based training devices for the laser and infrared Maverick will provide proof of concept opportunities for the proposed Phase I and Phase II SBIR effort.
