Suppression of the Residual Radiation of Ultrashort-Pulse Antennas in Packet Mode

摘要

Pulses radiated by ultrashort-pulse antennas [1, 2] are significantly distorted compared to an input signal produced by an ultrashort-pulse generator and applied to the antenna input. In particular, the radiated signal is more prolonged. To suppress this residual radiation, we suggested in [3] application of an extra corrective pulse (corrective action) to the antenna input after the input pulse. This corrective pulse is calculated so that radiation is completely suppressed to a given time. The second problem of the correction of the output signal is the best fit of its time diagram to a given shape. This problem was solved in [4] also by using extra corrective pulses applied to the antenna input simultaneously with the input signal of the ultrashort-pulse generator.
