研究了用GPS测定基阵坐标,分析了水听器基阵所接收到的声脉冲信号的处理。
This paper studies the determination of datum station with GPS and the computation problems of the sound pulse signal received by the datum station of echo pulse receiver under water.
工作中的水听器基阵所处的姿态不总是唯一的,为了计算水听器基阵的信噪比增益,我们必须知道噪声场空间任意方向上的相关系数。
For the calculation of signal-to-noise gain of a hydrophone array, spatial-correlation in arbitrary direction is more needed because of the variant pose of the array in the real.
