This paper considers the problem of tracking and intercepting a potentially moving ground-based RF source with an autonomous guided munition that has a passive bearings-only sensor located on its nose. It is assumed that the munition has lost GPS signal lock and that it relies only on its noisy inertial measurement unit IMU for guidance and navigation. Bearings-only target motion analysis TMA algorithms are used to obtain a position and velocity estimate for the RF source using the position, velocity and attitude estimates of the munition as well as the azimuth and elevation measurements obtained from the bearings-only RF sensor. Six degree-of-freedom 6-DOF and three degree-of-freedom 3-DOF munition models are used to evaluate the tracking and interceptseeker performance of a hybrid coordinate HC extended Kalman filter EKF, a particle filter PF, a multiple hypothesis MH HC-EKF, and a pseudo-linear least squares PLLS filter.
