N2 - The fractional Fourier transform (FrFT) is a potent tool to analyze the chirp signal. However, it fails in some applications, such as the echo is NFLM signal when the radar detects the high speed target. The short-time fractional Fourier transform (STFrFT) is proposed to solve this problem. It displays the time and FrFD-frequency information jointly in the short-time fractional Fourier domain. According to characteristic of high speed target, we establish the echo signal model with high-order phase, then analyze the target detection performance by numerical simulation to get the relationship among the optimal number of pulses, signal-to-noise ratio and acceleration changing rate. Finally, the simulations verify that the principle of the method is correct and can provide guidance for practical applications.
