| 中文摘要: |
| 众所周知，利用阵列处理技术实现多波束形成是大多数声呐和雷达系统的关键步骤。波束形 成技术发展多年，己较成熟。本文讨论利用被动声呐的阵列输出以检测和定位宽带声源的多波束形 成方法。所用芯片为 ＡＤ公司推出的最新 ＤＳＰ芯片 ＡＤＳＰ－２１０６０ ＳＨＡＲＣ。对于时域偏重于讨论 技术实现，对于频域则讨论实验模拟，并根据芯片特点对两种方法进行了比较。 |
| 英文摘要: |
| It’s well known that an important step in most Sonar and Radar systems is to implement multi-beamforming with Army-Processing Technology. Beamforming methods have been developed for a long time. This paper presents some multi-beamforming methods with passive Sonar’s array output, which can be used to detect and locate wideband underwater source. In implementation, we use Analog Device Company’s newest DSP chip-ADSP-21060 SHARC. We discuss implementation in Time-domain but simulation in Frequency-domain. The comparison of these two methods is presented also in this paper. |
