Abstract

This paper deals with a method of transmitting depth information of a high-speed underwater vehicle. The depth information signal transmitted from the high-speed mobile object is received with high frequency variability. In the proposed method, we apply not only frequency synchronization but also additional synchronization on the time axis like the existing method. In the case of a Doppler frequency bank with less resolution than the conventional method through simulations performed in the environment moving up to 50 kn, and the depth information is recovered using the proposed method, the error rate of 6 % ~ 9 % is reduced to 0.2 % ~ 1 %.
高速水下航行器深度信息传输的信号同步方法
本文研究了一种高速水下航行器的深度信息传输方法。高速移动物体发射的深度信息信号具有高频变异性。在该方法中,我们不仅采用频率同步,而且像现有方法一样在时间轴上进行额外的同步。在多普勒频率组分辨率低于常规方法的情况下,通过在移动至50kn的环境中进行仿真,利用该方法恢复深度信息,将6% ~ 9%的错误率降低到0.2% ~ 1%。
