Abstract: The system and method for EO/IR and RF sensor fusion and tracking using a dual extended Kalman filter (EKF) system provides a dynamic mixing scheme leveraging the strength of each individual sensor to adaptively combine both sensors' measurements and dynamically mix them based on the actual relative geometries between the sensors and objects of interest. In some cases the objects are adversarial targets and other times they are assets.

Abstract: An integrated architecture and its associated sensors and processing software subsystems are defined and developed allowing a conventional unguided bullet to be transformed into a guided bullet without the use of an on-board inertial measurement unit (IMU). Some important SW components of the present disclosure include a target state estimator (TSE); a bullet state estimator (BSE); Multi-Object Tracking and Data Association; NTS GL; and a Data Link. Pre-conversion of two angles and range information of an OI sensor from spherical coordinates into Cartesian coordinates eliminates the Jacobian dependency in the H matrix for the BSE, thus increasing the miss distance performance accuracy of the bullet target engagement system.
