K-pulse techniques for short-pulse radiation from dipole arrays

An investigation of K-pulse techniques to transmit short-time duration pulses from dipole arrays is presented. The array is analyzed from a radiation standpoint using the singularity expansion method. The analysis also makes use of the method of moments to express the array's radiation in terms of the terminal voltages and pole singularities. Following a numerical search in the complex frequency plane (from which the dominant singularities of the array are located), the time-domain waveform of the approximated K-pulse voltage is constructed. Calculated plots of the far-zone radiated electric field resulting from applying these voltages at the array terminals are presented, and their energy concentrations are compared to those of the optimum solutions.<
