Description
Summary:An automated method has been implemented in MATLAB(registered) to compensate for signal dispersion in antenna structures. We have explored postprocessing techniques that involve frequency transforms and deconvolution. The method has been applied to transient signals measured from a variety of different antennas and impulse sources. The technique has proved to be a valuable tool in reconstructing fast transient signals with inexpensive high-gain log-periodic antennas instead of more expensive, high fidelity wideband horns.
