The calculations of radar target ranges using multiple pulse repetition frequencies (PRI's) are considered for cases where one or more range measurement errors occur. It is assumed that target ranges are quantized into integer range gate numbers. To calculate the range gate number X for a target, an ambiguous range gate number is measured for each PRF. The number X is represented by a code word whose components are the ambiguous range gate numbers. A table is constructed consisting of all possible code words and the corresponding values of X. Given a code word from a target the corresponding number X is determined by searching the table for the closest match. It is shown that by setting maximum values for X, errors m the range gate numbers can be detected or corrected
