<p><P>PROBLEM TO BE SOLVED: To provide a Doppler transmission device based on a correlation process for easily and highly precisely detecting a detection object. <P>SOLUTION: The Doppler radar transmission device includes: a variable frequency oscillating unit 414 that adjusts a frequency spectrum of a transmission wave based on a travel speed to be an object of detection out of travel speeds of the detection object, an own travel speed and a propagation rate of a radar wave such that frequency spectra of the reflecting wave from the detection object and a predetermined reference wave whose auto-correlation is calculated in a Doppler radar receiving device, become identical; a read address generating unit 415; and a transmission wave applying unit for applying the transmission wave to the detection object. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
