Kalman-based moving object tracking using nonuniform pulse transmission scheme

This paper presents a radio-based real-time moving object tracking method based on Kalman filtering using phase-difference compensation technique and nonuniform pulse transmission scheme. Conventional methods often require time, amplitude, phase information and their derivatives for each receiver antenna, however its location estimation accuracy does not become good even with many transmitting pulses. The present method employs relative phase-difference information and nonuniform pulse generation scheme, which can greatly reduce the number of transmitting pulses while preserving the tracking accuracy. Performance of the proposed method is evaluated in comparison with that of the conventional method.
