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.
