Research on Calculation of Radial Acceleration of Maneuvering Target within One Pulse Echo

For fixed carrier frequency transmitting pulse, the acceleration of maneuvering target will cause change of square phase of echo signal. In this paper, the shot time fractional Fourier transformation (FRFT) is used to analyze one radar pulse signal. And then the relation between peak of transformation domain and pulse width is deduced quantificationally. In succession, the relation between single-noise ratio and the shortest pulse width necessary to get acceleration is discussed. Lastly, simulations have been made to verify the theoretical results
