Abstract: A video processor for a track-while-scan radar system, wherein each radar return, within a tracking window, is given a range weight corresponding to the range bin within the range sweep and an angle weight corresponding to a sweep count, which is initiated at the commencement of the tracking window. The weights for each return are summed to obtain a range weighted sum and an angle weighted sum, each sum then being coupled to a computer along with the total number of radar returns recorded within the tracking window. The video processor, on information supplied by the computer, establishes an annular ring about the radar system within which radar returns are sought.

Abstract: A radix converter comprises a plurality of automata each of combined Moore and Mealy design. The automata are connected in cascade with the digits of the input number applied serially to one of the automata. The Moore output of each automaton stage is utilized to provide the final state of the stage and is representative of a respective coefficient of the number in the transformed radix. The Mealy output of each stage is an untransformed residue transferred to the next identically designed automaton circuit. For numbers of integral value each automaton operates in accordance with the equation: ##EQU1## For numbers of fractional value each automaton is instrumented in accordance with the equation: ##EQU2## Where in the above equations: S = Present state of the stage S* = Next state of the stager.sub.a = Current radixr.sub.b = Desired radixZ = Mealy output to the next stageI.sub.0 (r.sub.a).sup.0 = Weighted input or residue digit in integral number conversionI.sub.-.sub.1 (r.sub.a).sup.-.sup.
