| 中文摘要: |
| 根据矢量水听器的测向原理和算法,提出了一种利用目标方位角的变化实现水下运动目标低频高精度的报警方法。该报警系统以水下设施为平台,对靠近设施的运动目标的方位进行跟踪测量,并在目标距离水下设施最近时给出报警信号,以达到有效地避免事故的目的。与传统的利用声级变化报警或主动回波测距报警方法相比,该方法具有低频、作用距离远和高精度的特点。 |
| 英文摘要: |
| Based on the theory and algorithm of the vector hydrophone, a method of sounding alarm from the azimuth angle detecting system when a target is closest is presented. The azimuth angle detecting system can be fixed on underwater facilities. It will follow the track of an approaching target and give an alarm to avoid accident when the target is at the closest position. Compared with the traditional methods which give alarm depending on sound intensity change or distance change calculated by an active echo, this method has the outstanding characteristics of lower frequency, longer operation distance and higher precision. |
