Abstract: A method and apparatus is provided for avoiding pattern blockage due to scatter from an object in which an artificial surface directs the energy from the antenna prior to arriving at a blocking structure such that either the wave fronts of the energy are linear when they arrive at the blocking structure or the phase of the energy incident on the object is adjusted such that the energy reflected from the object is in phase with energy directly from the antenna radiating elsewhere in the far field pattern, or both.

Abstract: A system and method of reducing or eliminating training for adaptive receiver and neural networks is disclosed. The adaptive filter or neural network is pre-training using simulation or empirically received data and a took-up table is created. Coefficient instantiation from the receiver for ail permutations of the key parameters of training data are stored along with the key parameters within the look-up table. After creating the look-up table, the key parameters of the signal to be decoded are estimated. The coefficient of filter or neural network for the estimated key parameters is obtained by accessing the loop-up table. The demodulated signal is produced by setting the filter or neural network coefficents to coefficient values obtained from the look-up table. For slow varying key parameters, the coefficients from the lookup table are occasionally replaced instead of implementing the adaptive filter or neural network.

Abstract: Techniques are disclosed that can be used to increase the dynamic range of a microchannel plate (MCP) device, thereby eliminating the need for conventional techniques such as gating. In one example embodiment, an MCP device is provided that includes a plurality of channels, each channel for amplifying a photoelectron input to the channel and for producing an electron cloud at its output. The device further includes one or more charging switches associated with each channel for allowing charging current to flow so as to charge that channel in response to producing an electron cloud. In some such example cases, the plurality of channels and the one or more switches are implemented in silicon, and the one or more charging switches turn on only in the presence of the electron cloud produced at the corresponding channel output.

Abstract: The system in one embodiment relates to tightly integrating parameter estimation, symbol hypothesis testing, decoding, and rate identification. The present invention provides Turbo-decoding for joint signal demodulation based on an iterative decoding solution that exploits error correction codes. The system iteratively couples an initial amplitude estimator, a symbol estimator, a bank of decoders, and a joint amplitude estimator to produce the symbol estimates.

Abstract: A system and process for testing and analyzing a laser beam is provided. The system and process allows for repeatable testing of a laser beam to provide a beam intensity profile while accounting for variation in measurements attributable to outside factors. The system and process further allows for simultaneous measurement and analysis of a laser beam having multiple wavelengths.

Abstract: A method of weather observations by a constellation comprises at least a first cluster of three micro-satellites each orbiting around earth, and each micro-satellites comprises a spectrometer. Orbiting the three micro-satellites of the first duster around the earth in three separate orbits offset with respect to one another. Staggering the three micro-satellites with respect to one another as they orbit. Selecting the offset and the staggering, of each of the three micro-satellites with respect to one another, so that each one of the three micro-satellites have a substantially identical viewing area as each one of the three micro-satellites orbits around the earth. Sequentially collecting observations, from each of the three micro-satellites, as the micro-satellites orbit around the earth and observe substantially identical viewing areas, to separately gather atmospheric measurements and provide critical data for weather forecasting by infrared temperature and humidity soundings and motion vector winds of the earth.

Abstract: Methods and systems for filtered image data recovery using lookback include storing first, second, and third data captures received from the image sensor in a first memory component and a second memory component. The methods and systems also include identifying a second detection in the second data capture and a third detection in the third data capture by filtering the first, second, and third data captures. The second detection and the third detection each exceed a pixel intensity threshold. The methods and systems also include correlating the second detection and the third detection to identify at least one track. The methods and systems also include detecting a first detection in the first data capture stored in the second memory component, the first detection being a pixel intensity value that is less than the threshold or an initiation event having a pixel intensity value that is less than the threshold.

Abstract: Embodiments of the invention are directed to methods and apparatus for infrared imagers including fast electrostatic shutters and offset compensation. Fast electrostatic shutters are used for video image correction including image offset compensation where temporal noise and scene nonuniformity are corrected. This method provides a shutterless experience for the user because the image will be blocked for only one frame at a time. A method of manufacturing an electrostatic infrared shutter includes a conductive infrared-transparent substrate, covering it with an insulating layer, depositing adhesive and a thin film stack, delineating a working area, providing contacts, heat-treating the assembly, and making the polymer non-reflective in the infrared.
