Abstract

A novel technique for dynamically forming and steering ultrawideband nulls in the far-field pattern of a time-steered array antenna is demonstrated. The transmitter system is based upon a fiber-optic dispersive prism design which generates an ultrawideband transmit beam as well as the required nulling waveform which is then properly time-steered. A four-element system is demonstrated in a compact antenna range showing null depths in excess of 15 dB over the 4 to 18 GHz bandwidth of the system for various main beam and null steering angles.
