Abstract

PURPOSE: To enable distance measurment, by sequentially selecting the main stations of a plurality in commonly using electromagnetic waves without synchronism, through the adoption of the call answer back system.
CONSTITUTION: The main stations 11W1N provide the antenna 4 performing transmission with a certain satisfied condition and being in reception state at all times, main station itself 5 performing measuring operation of distance, switch set controlling the antenna 4, main station control unit 7 controlling the main station itself 5 and the switch set 6. The control slave station 2 provides the antenna 8 and the control slave station controller 10 controlling the slave station itself 9 and operating the sequential callout of the main station 11W1N. Normally, the slave station 3 provides the antenna 11 and the slave station itself 12. The main stations 11W1N transmit the distance measuring signal on the carrier, and the control slave station 2 receiving it transmits the distance measuring signal on the carrier, and similarly, the slave station 3 receiving it transmits the distance measuring signal on the carrier.
