Phase linearization of a broad-band antenna response in time domain
John L. Volakis, J. Young · IRE Transactions on Antennas and Propagation · 1982
Broad-band antennas often introduce phase distortions to their associated signals. A digital technique is introduced to correct (linearize) the antenna phase response in the time domain without use of the fast Fourier transform (FFT) which in a minicomputer requires extensive computer time and storage for its implementation. The process can be performed in real time. It is accomplished by appropriately piecewise linearizing the phase response and correcting each linear phase (constant time delay) segment with respect to a time reference. The correction is performed with the application of a relative time delay and phase offset.
