摘　　要：采用简正波理论对浅海水声损失进行了研究和计算,浅海中的目标声源通过海水传播到海底引发地震波,对海底地震波的初至波和面波进行提取,得到了海底检测点到达海底震源的距离,目标的垂直方向不变,进而得到径向距离,采用卡尔曼滤波技术对目标进行跟踪。仿真结果表明,可以快速地跟踪上目标的运动状态,对浅海目标跟踪具有重大意义。The shallow water losses are studied and calculated by Jane positive wave theory, sound source of shallow water target will trigger seismic waves, through the shallow water propagation. Then extracting is done about the primary wave and surface wave. So the distance from detection point to the source of the seabed can be obtained. Vertical orientation of the target is constant, then the radial distance will be calculated. The target is tracked by kalman filter technology. The simulation results show that it can quickly track the state of the target. It has great significance for shallow water target tracking.
