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...
According to characteristic of ballistic missiles and their velocity, acceleration and jerk in radar echo, we establish the echo signal model with high-order phase echo signal characteristics, then analyze the target detection performance by numerical simulation to get the relationship among the optimal number of pulses, signal-to-noise ratio and jerk. Finally, the simulations verify the principle...
