Paper Abstract

Developed by Sagem (SAFRAN Group), the AASM is a modular Air-To-Ground "Fire and Forget" weapon designed to be able to neutralise a large range of targets under all conditions. The AASM is composed of guidance and range enhancement kits that give bombs, already in service, new operational capabilities. AASM Guidance kit exists in two different versions. The IMU/GPS guidance version is able to achieve "ten-meter class" accuracy on target in all weather conditions. The IMU/GPS/IR guidance version is able to achieve "meter class" accuracy on target with poor precision geographic designation or in GPS-denied flight context, thanks to a IR sensor and a complex image processing chain. In this night/day IMU/GPS/IR version, the terminal guidance phase adjusts the missile navigation to the true target by matching the image viewed through the infrared sensor with a target model stored in the missile memory. This model will already have been drawn up on the ground using a mission planning system and, for example, a satellite image. This paper will present the main steps of the procedure applied to qualify the complete image processing chain of the AASM IMU/GPS/IR version, including open-loop validation of ATR algorithms on real and synthetic images, and closed-loop validation using AASM simulation reference model.
