Abstract: System and method for determining range to targets using an M-of-N range resolver includes transmitting multiple coherent processing interval (CPI) signals with different pulse repetition frequencies (PRFs) towards the targets, receiving and storing threshold hits from prior N?1 CPIs; converting the threshold hits from the current CPI and prior N?1 CPIs to range unfolded threshold hits; generating a lookup table of the plurality of range unfolded threshold hits from the prior N?1 CPIs; determining the number of the prior N?1 CPIs in which a range unfolded threshold hit from the current CPI has at least one range coincident range unfolded threshold hit from a prior CPI utilizing the lookup table; generating a range resolved threshold hit when the number is greater than or equal to M?1; accumulating range resolved threshold hits; and determining the range to the targets.
