Abstract
A Doppler correlation technique to extract target velocity data in MPRF (medium pulse repetition frequency) radars by starting from ambiguous measurements is presented. A two-step procedure that assures satisfactory performance for a multiple target environment and frequency agile radars is proposed. The performances have been assessed through a computer simulation which allowed the selection of the best values for Doppler coincidence threshold K and filter enlargement beta . In particular, the values K=L-1 and beta =30% represent the best tradeoff, since they give a probability of correct velocity resolution greater than 99.5%. It is shown that the velocity correlation algorithm can also operate as a deghosting filter.<>
