利用目标俯仰角和多途时延联合对目标定位适用于小尺度平台,具有重要的应用价值。通过数值仿真分析了接收深度测量误差、目标俯仰角测量误差、多途时延测量误差和海水声速测量误差等因素对目标定位精度的影响。得出结论:目标俯仰角和多途时延的测量误差是影响目标定位精度的主要因素,而接收深度和海水声速测量误差属于次要因素。 The combination of target pitch angle and multi-way delay is suitable for small-scale platform for target location, which has important application value. The impact of the receiver depth measurement error, the target pitch angle measurement error, the multi-way delay measurement error and the seawater velocity measurement error on the target location accuracy is analyzed by numerical simulation. It is concluded that the measurement error of the target pitch angle and multi-way delay is the main factor affecting the positioning accuracy of the target, while the receiving depth and the measurement error of seawater velocity are secondary factors.
