摘要
相控阵多普勒计程仪具有基阵体积小,无需进行声速补偿等优点。本文在讨论相控阵多普勒计程仪原理的基础上,推导了速度解算公式,验证出公式与声速无关,进而推导出声基阵的输出信号模型,利用此模型便可模拟相控阵的输出信号。
The phased-array Doppler log has several advantages, such as small the size of array and no need of compensation for sound velocity. Prom the array theory, the velocity formula is deduced. It is proved that the velocity formula does not involve the acoustic velocity in water. Then, the signal model of the acoustic array output is analyzed. The output signal of the phased-array can be simulated by this model.
