POSITION MEASURMENT APPARATUS FOR MEASURING POSITION OF MOBILE OBJECT ON THE BASIS OF REFELECTED WAVE |
摘要 |
A reflector apparatus includes reflectors, which respectively radiate reflected waves in predetermined polarization directions. A polarized wave information reading circuit fixed to a moving body radiates a radio wave toward the reflecting apparatus from a transmitting antenna, receives reflected waves from the reflecting apparatus, and generates a received level difference signal that corresponds to a polarization direction of the received reflected waves. A position calculating circuit calculates a position of the polarized wave information reading circuit based on the received level difference signal. |
