(Partial Matching Filter)PMF-(Fast Fourier Transformation)FFT algorithm has advantages in acquisition speed and hardware complexity. However in Doppler frequency acquisition there is a contradiction between acquisition accuracy and hardware complexity. In addition the range of frequency acquisition is limited. What's worse in this limited and small range, the peak of output seriously decline with the increasing of Doppler frequency. To solve problems above, first of all this paper analyzed the… CONTINUE READING
