Conventional medium pulse repetition frequency (PRF) processing applies a double thresholding system of detection. First, within each coherent processing interval (CPI), signals in each range/velocity cell within the unambiguous range and unambiguous velocity space are compared with a threshold level to declare whether a target is present. These target detections are ambiguously repeated across the range/velocity space of interest. This process is repeated for all N CPIs; each CPI operates on a different PRF. Second, each range/velocity cell is subjected to a binary integration process, which is looking for target detections in the same range/velocity cell in M out of the N CPIs. A target is declared if detected in a consistent range/velocity cell in at least M of the total of N CPIs.
