Temporal-Spatial Compression Antennas

摘要

The idea of using an antenna as a pulse compression network is presented employing the natural dispersion inherent in some broadband antennas. It is shown that the power densities resulting from such antennas are increased by the time-bandwidth product of the antenna over its 'CW' power density. Experimental measurements have been performed on two (2) antennas to determine their transfer functions. Both the circular-polarized cavity-backed spiral and the linearly- polarized pyramid log periodic antennas have excellent chirp transfer functions and the results are given. (Author)
