Patent ID: 7557747

Claim:
An electromagnetic receiver array system comprising: a plurality of receiver antennae for receiving electromagnetic pulses; a switching device associated with said receiver antennae and capable of causing each said receiver antenna to be in one of an active state and an inactive state, wherein when a said receiver antenna is in said active state said receiver antenna is receptive to electromagnetic pulses, and wherein when a said receiver antenna is in said inactive state said receiver is not receptive to electromagnetic pulses; a switch control circuit associated with said switching device and capable of controlling said switching device so that at any given time one said receiver antenna is in said active state and every other said receiver antenna is in said inactive state, and so that said receiver antennae are sequentially cycled through said active states; and means for emitting electromagnetic pulses, said means for emitting electromagnetic pulses being associated with said switch control circuit; wherein each said receiver antenna is in said active state for a duration commensurate with a selected number of emitted electromagnetic pulses, wherein each said receiver antenna is in said active state for the same said duration, wherein said emitted electromagnetic pulses are characterized by a wave table, and wherein said switch control circuit is characterized by logic whereby each said duration equals the product of the number of frequencies in said wave table times the number of pulse integrations in said wave table.
