Abstract: An apparatus has a Radio Frequency (RF) signal generator to produce RF signals phase shifted relative to one another in accordance with RF frequency waveform parameters. Amplifier chains process the RF signals to produce channels of amplified RF signals. Each amplifier chain has amplifiers and at least one amplifier has a tunable gate voltage synchronized with the RF signals.

Abstract: An array of antennae includes a monobit transmitter to insert dither into a transmit signal to form a dithered transmit signal. Monobit receivers process received signals that are combined with the dithered transmit signal to form composite received signals. Digital down converters process the composite received signals to form down converted received signals. A beamformer circuit processes the down converted received signals to form recovered signals.

Abstract: In one embodiment, a countermeasure system for protecting an asset from a missile attack includes a decoy comprising a plurality of quantum dots selected to emit radiation having a radiation emission profile similar to a profile of a radiation signature of the asset. In another embodiment, a method of simulating a radiation signature of an asset using quantum dots includes dispersing quantum dots to form a cloud of quantum dots; and exciting the quantum dots with a first radiation so that the quantum dots emit a second radiation having a profile similar to the radiation signature profile of the asset.
