Abstract:
The double pulse sources method (DPS) is presented for linear track estimation in this work. In the field of noise identification of underwater moving target, the Doppler will distort the frequency and amplitude of the radiated noise. To eliminate this, the track estimation is necessary. In the DPS method, the bearings of two sinusoidal pulse sources installed in the moving target are estimated through baseline positioning method in the first step. Meanwhile, the emitted and recorded time of each pulse are also acquired. Then the linear track parameters will be achieved based on the geometry pattern with the help of double sources spacing. The simulated results confirm that the DPS improves the performance of the previously presented double source spacing method. The simulated experiments were carried out using a moving battery car to further evaluate its performance. When the target is 40~60m away, the experiment results show that biases of track azimuth and abeam distance of DPS are under 0.6o and 3.4m, respectively. And the average deviation of estimated velocity is around 0.25m/s.
