中文摘要:
      文章对目前常采用的定位方法进行了分析,提出了用双直角三角形阵对声目标进行定位。该方法采用虚拟传声器技术,用较少的传声器能达到主从式正四方形阵的定位效果,从而解决了单四方形阵不能远距离定位的问题。通过仿真计算给出了各种误差对测向和测距精度的影响曲线,结果表明,该方法具有较好的定位性能。
英文摘要:
      The paper analyzes various methods of target location,and presents a method of acoustic target location with a dual right triangle array.The method uses a fictitious acoustic sensor technique,and,with fewer acoustic sensors,can realize the same location performance as that obtained by using a primary accessory square array.It has solved the problem that a square array is unable to locate targets in distance.Curves showing the effects of errors on the accuracy of bearing and range measurements are obtained through numerical computations.The results show that the method has a good location performance.
