Parabolic-array beam forming for nonsinusoidal waves

A beamforming method for nonsinusoidal waves using parabolic arrays is described. Antenna patterns for rectangular and sinusoidal pulses are given. Patterns for radiated signals with arbitrary time variations are shown to be derivable through function approximation by sums of linear ramp functions....

Zusammenfassung:	A beamforming method for nonsinusoidal waves using parabolic arrays is described. Antenna patterns for rectangular and sinusoidal pulses are given. Patterns for radiated signals with arbitrary time variations are shown to be derivable through function approximation by sums of linear ramp functions. In addition, the related far-field transient of signals that are zero for tor=0 is described. A number of computer simulations are also given.< >
