Abstract
The performance deterioration that sets is when a circular array is scanned fast using the method of frequency scanning is considered. The high-speed effects are a loss in the main-beam amplitude and a change in sidelobe level. However, in contrast with the case of a linear array, the circular array is relatively free from variations in the beamwidth or generation of spurious frequencies. Specific examples in radar and sonar are discussed.
