Abstract

A radar system comprises a plurality of radar devices that detect an object by monitoring different areas. Each of the plurality of radar devices includes a display device. When the object is detected by any one of the plurality of radar devices, a display device of a first radar device that has detected the object produces a display indicating that the object has been detected, and a display device of a second radar device different from the first radar device produces a display indicating a position of the first radar device.

Claims (16)

1 . A radar system comprising a plurality of radar devices,

wherein each of the plurality of radar devices is installed at a location configured to monitor a corresponding one of a plurality of monitoring areas and detects an object by monitoring the corresponding area,

each of the plurality of radar devices includes a display device, and

when the object is detected by any one of the plurality of radar devices, a display device of a first radar device that has detected the object produces a display indicating that the object has been detected, and a display device of a second radar device different from the first radar device produces a display indicating a position of the first radar device.

2 . The radar system of claim 1 , wherein the display indicating the position of the first radar device includes a display indicating a direction of the first radar device with respect to the second radar device.

3 . The radar system of claim 2 , wherein the display indicating the position of the first radar device includes a display indicating a distance from the second radar device to the first radar device.

4 . The radar system of claim 1 , wherein the display indicating the position of the first radar device is a display indicating coordinates of the first radar device.

5 . The radar system of claim 1 , wherein the display indicating that the object has been detected is a display indicating coordinates at which the object was detected.

6 . The radar system of claim 1 , wherein the display indicating that the object has been detected is a display in which the position of the object is superimposed on a map indicating an area monitored by the first radar device.

7 . A detection result display method using a radar system including a plurality of radar devices that detect an object by monitoring different areas,

wherein each of the plurality of radar devices is installed at a location configured to monitor a corresponding one of a plurality of monitoring areas and detects an object by monitoring the corresponding area,

each of the plurality of radar devices includes a display device, and

when the object is detected by any one of the plurality of radar devices, a display device of a first radar device that has detected the object produces a display indicating that the object has been detected, and a display device of a second radar device different from the first radar device produces a display indicating a position of the first radar device.

8 . A radar device for detecting an object that is used together with another radar device, the radar device being installed at a location configured to monitor a corresponding monitoring area and detecting an object by monitoring the corresponding area, comprising:

a display device that produces a display indicating that an object has been detected when the object is detected by the radar device;

wherein the display device produces a display indicating the position of said another radar device that has detected the object when the object is detected by said another radar device.
