摘要/Abstract

摘要： 针对噪声源识别中水下近场高速直线运动目标的航迹估计问题，将双脉冲源方法扩展到三维空间中。该方法利用公垂线最小化，将基线定位方法估计的两个连续波脉冲参考源的定位结果投影到二维平面内，并结合已知的双参考源间距等信息构造航迹参数的目标函数，进而利用遗传算法估计三维空间内直线运动目标在各脉冲辐射时刻下的位置和航速。仿真结果表明，0 dB条件下当航向角和俯仰角均在\[-40°, 40°\]内时，其估计偏差均在3.8°以内，而正横距离和深度差的估计偏差在5.9 m以内。水库实验进一步验证了该方法的有效性。

Abstract: For the identification of noise source, the track information could be applied to Doppler compensation for the recorded noise emitted from moving vehicle. Linear track estimation of near-field underwater moving target by double pulse source (DPS) has been used successfully in 2-dimension. The use of DPS is extended to 3- dimension space in order to linearly track the target. The positioning result of double reference source obtained by the baseline positioning method is projected to a certain plane under the limitation of common perpendicular minimum length. The objective function of DPS is constructed with the known distance of double reference source. The track information in 3-dimension space is obtained by using genetic algorithm. The simulation results show that the estimated errors of azimuth and pitch angles are less than 3.8° when their trace line lies under \[-40°, 40°\] in case of 0 dB noise level. The estimated errors of abeam distance and depth difference are kept less than 5.9 m at the same time.
