Document Type and Number:
Japanese Patent JP2932210
Kind Code:
B2
Abstract:
PURPOSE:To receive and recognize correctly the reflected waves of only radar waves transmitted from one' s own motorcar and prevent the obstruction detection mistaken, by drawing an exact line between radar waves from one' s own motorcar and radar waves from the other motorcar. CONSTITUTION:A radar wave generating element to generate the radar waves for detecting an obstruction is constituted so as to be possible to generate plural frequencies different each other. Therewith, ID signals to recognize being the radar waves from one' s own motorcar are piled up to the said radar waves transmitted. Where the radar waves received by the discrimination making the said ID signals a reference are the radar waves of the other motorcar with the same frequency number as it of one' s own motorcar, the false detection by the input of the radar waves of the other motorcar is prevented by changing the frequency of the radar waves from the said radar wave generating element to the other frequency.
