Kalman Filtering of FDOA/TDOA Missile Tracking System

Abstract

The accuracy of a tracking system designed to determine the Time, Space and Position Information (TSPI) of an airborne missile by detecting its telemetry signal at a number of receiver sites is investigated. Doppler frequency measurements are converted to range differences between the missile and receiver sites, whose locations are known in three dimensions. An algorithm then utilizes these range differences to obtain the missile TSPI. The accuracy of the TSPI is a function of the measurement precision and the signal-to-noise ratio at the receiver sites. This thesis examines the characteristics of the TSPI accuracy and investigates how a Kalman Filter can be used to enhance the accuracy of the TSPI.
