Abstract: A method for increasing the MeV hot electron yield and secondary radiation produced by short-pulse laser-target interactions with an appropriately high or low atomic number (Z) target. Secondary radiation, such as MeV x-rays, gamma-rays, protons, ions, neutrons, positrons and electromagnetic radiation in the microwave to sub-mm region, can be used, e.g., for the flash radiography of dense objects.

Abstract: A solid state RADAR antenna system is provided comprising at least one antenna configured to transmit a plurality of antenna beams. Each antenna beam is decoupled from each of the other plurality of antenna beams for transmitting in a blind range of a different antenna beam. Accordingly, in an implementation, the second antenna beam is transmitted so as to scan a first blind range associated with the first antenna beam. Decoupling antenna beams can be achieved using one or more of physical decoupling using different antennas, frequency decoupling using different bands and/or frequency multiplexing, or orthogonal polarization.

Abstract: A novel and useful system and method by which radar angle and range resolution are significantly improved without increasing complexity in critical hardware parts. A multi-pulse methodology is described in which each pulse contains partial angular and range information consisting of a portion of the total CPI bandwidth, termed multiband chirp. Each chirp has significantly reduced fractional bandwidth relative to monoband processing. Each chirp contains angular information that fills only a portion of the 'virtual array', while the full virtual array information is contained across the CPI. This is done using only a single transmission antenna per pulse, thus significantly simplifying MIMO hardware realization, referred to as antenna-multiplexing (AM). Techniques for generating the multiband chirps as well as receiving and generating improved fine range-Doppler data maps. A windowing technique deployed in the transmitter as opposed to the receiver is also disclosed.

Abstract: According to a first aspect, the invention provides a pulsed radar comprising a transmitter; wherein the pulsed radar is arranged to generate a string of binary values; wherein the transmitter comprises a pulse generator arranged to generate a pulse signal comprising a series of transmit pulses with polarities determined in accordance with the string of binary values; wherein a first substring comprises a first series of values; wherein a second substring comprises a second series of values; wherein the second substring is different from the first substring; and wherein each value in the second series of values is either the same as or different from the corresponding value in the first series of values according to a repeating pattern; and wherein the string of binary values comprises at least the first substring and the second substring concatenated together and each optionally being reversed before concatenation. By transmitting two related series of pulses, the transmitter can achieve better noise cancellation and/or better rejection of reflections from unwanted ambiguity ranges. The repeating pattern can be selected so as to form a relationship between the polarities of reflections from one ambiguity range as they appear in a different ambiguity range. This relationship can be used to ensure cancellation of unwanted pulse reflections, while ensuring that the reflections of interest are summed, i.e. reinforced.

Abstract: A digitally implemented radio frequency sensor for physiology sensing may be configured to generate oscillation signals for emitting radio frequency pulses for range gated sensing. The sensor may include a radio frequency transmitter configured to emit the pulses and a receiver configured to receive reflected ones of the emitted radio frequency pulses under control of a microcontroller. The received pulses may be processed by the microcontroller to detect physiology characteristics such as motion, sleep, respiration and/or heartbeat. The microcontroller may be configured to generate timing pulses such as with a pulse generator for transmission of radio frequency sensing pulses. The microprocessor may sample received signals, such as in phase and quadrature phase analogue signals, to implement digital demodulation and baseband filtering of the received signals.
