摘要: Broad-band antennas often introduce phase distortions to their associated signals. A digital technique is introduced correct (linearize) the antenna response in time domain without use of fast Fourier transform (FFT) which a minicomputer requires extensive computer and storage for its implementation. The process can be performed real time. It accomplished by appropriately piecewise linearizing correcting each linear (constant delay) segment with respect reference. correction application relative delay offset.
