Patent attributes
The present invention relates to a target tracking method of radar with frequency modulated continuous wave, which transmits a transmitted signal to receive a return wave of the transmitted signal that is used for detecting the target and obtaining the relative distance between the target and the radar. The target tracking method includes transmitting a frequency modulated continuous wave and receiving the reflected wave; getting a reflected wave corresponding to the target by detecting the reflected wave; getting a range gate error by seeking the plurality of the range gates corresponding to the reflected wave; and getting a position and a speed of the target at next time by knowing the position of the target at present time basis of the range gate error. Hence, the relative distance between the radar and the target is got.
