ABSTRACT:
A system for transmitting and receiving very wide instantaneous bandwidth signals. Synchronized short pulse generators are positioned at the feed location of each element of a linear array of short capped monopole antennas to sequentially excite the antenna elements which are spaced in accordance with the sequential interval to provide a beam in the desired direction and space. Reflections of the radiated short pulses are received by a feed monopole backed by a reflecting monopole and coupled to a short pulse receiver through a duplexing switch.
