| 中文摘要: |
| 为了解决单水听器对运动目标的被动测距的问题，提出了一种基于最小二乘的脉冲周期最接近法。该方法适用于目标发射固定周期脉冲信号，推导了目标运动参数与单水听器接受信号脉冲周期的关系式，构建一个长方矩阵，在最小二乘意义下，计算目标最接近距离和速度。使用泰勒展开公式，分析了算法的误差特性。为单水听器被动测距提供了新方法。仿真结果表明了新方法的正确性。 |
| 英文摘要: |
| In order to solve the problem of single hydrophone passive ranging, a method of pulse periods closest point passive ranging based on the least squares method is proposed. This scheme is suitable to the target which is transmitting fixed periods pulse. This method deduces the function between kinematics parameter and pulse periods signal which is received by a single hydrophone, and constructs a rectangular matrix and uses the least square principle to obtain the least square solutions of target distance and speed. The error of the algorithm are analyzed using Taylor expansion formula. This method allows new approach to single hydrophone passive ranging. Simulation results show its correctness. |
