Abstract

PURPOSE: To enable the course and the speed of a sound emitter and a rang from a sound wave receiver to the sound emitter to be measured by a simple constitution by using the access bearing and the frequency of a sound wave received by the one receiver at different times.
CONSTITUTION: Signals received by a receiver at different times are calculated by a frequency detecting circuit 2 and a bearing detecting circuit 3 with a received frequency and a received bearing and latched by latching circuits 4 and 5, respectively. A course calculating circuit 6 calculates the course θT of a sound emitter on the basis of access bearing data θ1Wθ3 and frequency data f1Wf3 at the different times. A speed calculating circuit 7 calculates the speed of the sound emitter on the basis of the received bearing data θ2 and θ3, the received frequency data f2 and f3 and course data θT. A range calculating circuit 8 calculates a range from the receiver to the sound emitter on the basis of the data θT-θ2 and θT-θ3 on the bearing and the course of a received sound wave, respectively, and speed data (v).
