- W2366947983 abstract "When the transmitted signal is linear frequency modulation(LFM) signal,the performance of velocity estimation based on narrow ambiguity function is degraded in wideband system.Because target velocity will caused scaled version signal,the echo is still a LFM signal.And the LFM energy in Fractional Fourier Transform Domain can be centered.Then the velocity estimation method based on the scale properties of Fractional Fourier Transform was proposed.The relationship between the order of FRFT and target velocity was derived and the effect of the order on estimated velocity was analyzed.At last,the numerical simulation shows that the proposed method can estimate the velocity of high speed target and has higher accuracy." @default.
