| 中文摘要: |
| 相控阵多普勒计程仪具有基阵体积小,且无需迸行声速补偿等优点。本文在讨论相控阵多普勒计程仪原理的基础上,提出了相控接收和宽带系统移相的方案。并通过试验验证了实际设计制作的相控接收系统的可行性。 |
| 英文摘要: |
| The phased-array Doppler log has several advantages, such as small size of array and no need of compensation for sound velocity. From the array theory, a phased receiving and wide-band phase-shift scheme for this kind of Doppler log is proposed in this paper. The feasibility of a built phase receiving system was proved by an experiment. |
