About 5775K to do Doppler fft 64

[yinlei]

Now that I'm having some problems, I'm doing a Doppler FFT of 64. The ADC samples are 64 chirp at 256, the range FFT at 256 FFT, the Doppler FFT at 64。I can refer to the Doppler FFT of 128, and now I've modified everything I can think of, but the program is still not correct。，
