摘要
根据水下测控基阵对目标测量的时延信息,提取反映速度变化的各基元时延差,提出一种新的测量水下目标速度的方法,并做误差分析、实测数据验证,其测量精度达到0.2kn以上,利用现有定位设备解决了水下目标高精度测速问题。
Based on the difference of target time-delay measured by different element of underwater acoustic array,a new method of measuring target velocity is proposed,and the error analysis is made.Testing data verify that the measuring precision reach 0.2 knots,and so the problem of measuring under-water target velocity can be solved by using the existing locating equipment.
