REFLECTOR, REFLECTIVE COATING, AND REFLECTING BODY DETECTING DEVICE

摘要

A reflector has a spherical main body and a plurality of conductor wires projecting radially from a central portion of the main body as the center. The reflector has a spherical shape like a sea urchin or chestnut in burr as a whole. At least any one conductor wire out of the plurality of conductor wires causes a radio wave entering while oscillating in a specific oscillating direction, to oscillate in a direction different from the specific oscillating direction, so as to reflect the radio wave in an incident direction in which the wave has entered. A radar device mounted on a flying object transmits a radio wave oscillating in the specific oscillating direction, and receives a radio wave oscillating in a direction different from the specific oscillating direction. If the signal intensity of the received radio wave is higher than a detection threshold, the radar device determines that there is a reflector in the direction the radio wave has been transmitted.

1. A reflector comprising:
a main body; and a plurality of linear radio wave scattering bodies provided to the main body in different orientations, wherein at least any one radio wave scattering body out of the plurality of radio wave scattering bodies causes a radio wave entering while oscillating in a specific oscillating direction, to oscillate in a direction different from the specific oscillating direction, to reflect the radio wave in an incident direction in which the radio wave has entered.
