Abstract: In order to transmit directly E-pulse for target identification, a general coefficient expression of the Fourier series for a special coded signal with a rectangle base is theoretically deduced in this paper. Then an E-pulse waveform synthesis method using Fourier series expression is proposed, as well as the principles for its parameters choice and system block diagram for E-pulse waveform synthesis. The target identification performance simulations of synthesis E-pulse and theoretical E-pulse based three finite thin wires scattering data show that the proposed method in this paper is effective.
