Abstract :
A new technique is described to resolve the ambiguities of wide field of view interferometers. The use of integer fractional baselines minimizes the number of additional elements since the ambiguities of the smaller baseline straddles those of the overall baseline. Finally, synthetic baselines can be obtained by arraying the elements with the minimum spacing. These synthetic baselines resolve any remaining ambiguities.
