Double-Equilateral-Triangle Array and Precision Analysis

Abstract:

The location and direction precision is passive acoustic technology of important technical index. Put forward a double-equilateral-triangle array of six elements. According to passive acoustic theory for the location algorithm. Azimuth and elevation Angle is deduced, and the distance of the error formula, through the simulation test, the time delay estimation error analysis of the influence of the location precision. Simulation results show that: double-equilateral-triangle array eliminates the sound velocity and the formation parameters diagonal coordinates estimation precision effect, which have practical significance.
