RANK ORDER PROCESSING ARRAY A rank cell array for ranking a series of sample values including a number of identical rank cells (RC1, RC2 ...) permitting ready modification of the sorting window size in an OS CFAR radar application, for example. Each rank cell (RC1, RC2 ...) includes a multiplexer (49), a D flip-flop (41), first and second comparators (43, 45), and a multiplexer controller (49). Each clock interval, the foregoing circuitry examines the sample value entering the sorting window, the sample value leaving the sorting window, the sample value in the preceding rank cell, and the sample value in the succeeding rank cell to determine the sample value in the rank cell during the next clock interval.
