| Abstract: | A simple practical implementation of positioning system with passive acoustic sensor arrays for localizing helicopter was presented. The system was composed of four acoustic sensors with a squared configuration, a multi channel synchronous signal collector, a high speed DSP, and servo control mechanisms. The correlation method for orientation estimation and Doppler based ranging estimation were also introduced. The experimental result showed that the system could reach a reasonable accuracy in many applications. |
