Radar System

摘要

A radar system includes a plurality of radar devices each having a transmitting unit that transmits a high frequency signal to an object, a receiving unit that receives a signal reflected from the object, an individual control unit that controls transmission and reception timings, and a converting unit that converts an output of the receiving unit into digital data, and a central processing device having an integration process unit that processes information transmitted from the radar devices in association with positional information of the radar devices, a command control unit that controls operation timings of the individual control units, and a detection process unit that performs a process for detecting the object on the digital data before being processed by the integration process unit. Digital communication isolated from the transmission and reception timing controls at the individual control unit is performed between the radar devices and the central processing device.

1. A radar system comprising:
a plurality of radar devices and a central processing device, each of the plurality of radar devices having: a transmitting unit adapted to transmit a high frequency signal to an object; a receiving unit adapted to receive a signal reflected from the object; an individual control unit adapted to control timings of transmission and reception by the transmitting unit and the receiving unit; and a converting unit adapted to convert an output of the receiving unit into digital data, the central processing device having: an integration process unit adapted to process a plurality of pieces of information transmitted from the plurality of radar devices in association with a plurality of pieces of positional information of the plurality of radar devices; a command control unit adapted to control operation timings of the individual control units of the plurality of radar devices; and a detection process unit adapted to perform a process for detecting the object on the digital data before being processed by the integration process unit, digital communication which is isolated from the control of timings of transmission and reception at the individual control unit of each of the plurality of radar devices is performed between the plurality of radar devices and the central processing device.
