| Abstract: | Single-observer passive location and tracking technology has many merits,such as simple equipment and independent system,and can be widely used in the engineering field.To improve the location precision and convergence speed and meet the real-time requirements,an algorithm based on the existing algorithm of Doppler changing rate is developed.A modified gain extended Kalman filter is introduced to solve the instability of extend Kalman filter.The performances of these algorithms are compared by computer simu... |
