体积混响下引信超声探测的双声定位

im at the request of fast position target to depth charge fuze, put forwards a position algorithm for ultrasound detection of using dual-sensor. By estimating the pressure difference and the time difference of dual-sensor, the algorithm effectively achieves the position. the algorithm gives the pressure difference position model and the time difference position model, and derivation out have been for resolved solutions of real-time position. The problem of mirror fuzzy of the linear array is resolved by dual-sensor rotating 90 degrees. The problem is solved by dual-sensor rotating angle that the algorithm is unable to position when the target is located in perpendicular bisector. Simulation results show that the algorithm under the condition of lower reverberation can achieve a good position. The Algorithm applies to the fuse, and other devices with volume requirements.
