MOBILE BODY FINDING DEVICE

摘要

PURPOSE:To obtain the mobile body finding device by utilizing the spread spectrum communication system. CONSTITUTION:A reception signal and a reference signal generated by a reference a bar PN code selected based on a control signal from a discrimination control circuit 303 with a selector 301 are given to a correlation device 307. When a correlation output signal is obtained, its detection output is compared with a reference value Er at a comparator 304 and the result of comparison is inputted to the discrimination control circuit 303. The discrimination control circuit 303 sends data with a reference number of the bar PN code and its own receiver number added to them to a monitor room 200.
