Abstract

A fast calculation method, based on three-dimensional (3D) point sources for calculating the time domain pattern of the large-scale pulsed array antenna, is proposed to calculate the time and space distribution of the radiation field under pulsed excitation. The array factor in the time domain is obtained by combining the principle of array superposition with the impulse radiation theory of 3D point sources. For different elements (antipodal Vivaldi antenna is used in this paper), we use the time domain solver of CST to obtain the pattern of elements. In addition, the method of extrapolating a small array to a large array is proposed to correct the effect of mutual coupling on the calculation results. The fast and accurate calculation of array radiation characteristics in the time domain by this method provides a theoretical basis for the analysis and comprehensive optimization of pulse array antennas.
