| 在三度空间水下武器弹道高精度测量系统中,航行深度是必不可少的测量参数之一。简要论述了同频双脉冲水声跟踪信号体制深度遥测及信号检测的原理,分析比较几种常用的深度信号检测方法,总结出一种有效可靠的检测途径。湖上实航跟踪试验结果表明,该方法能较大程度提高深度地信号有效检测概率,取得了良好的工程应用效果,具有较好的应用前景。 |
| 英文摘要: |
| Depth parameter is one of the most important parameters that must be measured in 3-D high precision underwater weapon trajectory measurement.The remote depth measuring method and the principle of signal detection based on same-frequency double-pulse underwater acoustics signal tracking system are briefly discussed.Several methods of depth signal detection are analyzed and compared,which result in an effective and reliable method.It is approved by at-lake test that the depth signal detection probability can be improved by using this method,which provides an attractive prospect of being used in other underwater weapon tests. |
