The present invention relates to a frequency modulated continuous wave speed measurement and distance measurement method. The method comprises the steps of S1 transmitting a frequency modulated continuous wave signal of which the frequency changes along a combined waveform modulating signal to N targets, and obtaining a corresponding beat signal; S2 carrying out the one-dimensional FFT processing of a fast time domain on the beat signals within a cycle TTa and a cycle TTb to extract the spectral peak frequencies corresponding to the N targets in the cycle TTa and the cycle TTb; S3 calculating to obtain the corresponding distance speed matrixes in the cycle TTa and the cycle TTb; S4 finishing the correlation matching of multiple targets to obtain the distance r and the unambiguous inaccurate speed v corresponding to each target; S5 calculating to obtain the ambiguous accurate speed vapre corresponding to each target; S6 calculating to obtain the unambiguous accurate speed vpre corresponding to each target. According to the present invention, by utilizing an improved modulating signal and combining a two dimension FFT method, the purpose of high-precision speed measurement and distance measurement can be achieved under a smaller FFT point number.
