Abstract
The PRI of Random PRI PD radar is non-uniform. This paper proposes that using NUFFT to estimate random PRI PD radar target velocity instead of using FFT, then analyzes the calculation complexity of NUFFT and NUDFT. The simulation and numerical results show that the velocity estimated by using NUFFT is more accuracy than FFT. The time spent by using NUFFT is less than NUDFT.
