In multi-dual frequency CW radar there are several methods of choosing frequency difference in de-ambiguous techniques in the measurement of range by phases. Three choosing methods are compared by computer simulation. Multi-frequency differences, which are reciprocal prime numbers has high precision on condition that the SNR is high. Multi-frequency differences, which are shown in the form of power-exponent can be used in the measurement of both dot targets and body targets. One big frequency difference and several little reciprocal prime frequency differences has good ability in anti-noise.\;
