Abstract: A counter measure system is provided having a unitary infrared transparent dome including a look angle greater than 180. The dome has two hemispherical regions, with a second region having a truncated bottom end defining an opening to a central cavity inside which electro-optical elements are disposed. The electro-optical elements can view outward through the dome at the look angle. The second region on the dome has a complementary curvature as the first region by continuing a similar radius beyond a transverse horizontal axis or equator. The dome is mounted to a base, which also may be referred to as a bezel. The base defines a rabbet extending circumferentially about the base imaginary center defining an aperture. The base and the dome are formed from different materials but have equivalent coefficients of thermal expansion. In one embodiment the dome if formed from sapphire and the base is titanium.

Abstract: An apparatus for securing an image sensor within a night vision scope is disclosed. The apparatus includes a flat washer, a crush bushing, and a fastener. The crush bushing is inserted through an opening of a corner anchor of the image sensor. A fastener receptacle is located at a module of the night vision scope. The fastener can be inserted through an opening of the flat washer and a bore of the crush bushing to deform the crush bushing such that the crush bushing material fills any space between the fastener and the fastener receptacle, thereby creating a zero-play connection to restrict any slight movements generated by shocks and vibrations.

Abstract: The system and method making and using a modular, scalable phased array antenna particularly for use on curved substrates. Surface resistors are used instead of vias to reduce the cost and to increase the configurability of the array. The array is frequency independent and can be used on flat or curved surfaces. The array can be printed as a PCB or printed using additive manufacturing.

Abstract: A proximity fuse includes an electric-field (E-field) sensor to detect electrical disturbances from an object that is external and distinct from a device carrying the proximity fuse. The E-field sensor detects or senses E-fields versus time in order to provide omnidirectional coverage of the device carrying the proximity fuse. When the device carrying the fuse is a missile having warhead, the proximity fuse is connected with detonation logic that detonates the warhead at a desired time to destroy or neutralize the object, which is typically a threat, such as another missile.

Abstract: A variable gain amplifier circuit including a first amplifier, a second amplifier, and a variable capacitor connected in series between the first amplifier and the second amplifier is disclosed. As a gain of the variable gain amplifier circuit varies, the input impedance, output impedance, noise figure and third-order output intercept point (OIP3) of the variable gain amplifier circuit remain unchanged.

Abstract: An image registration system and method for matching images having fundamentally different characteristics. One exemplary feature of the system and method includes the use of an enhanced phase correlation method combined with a coarse sensor model to hypothesize and match a custom match metric to determine a best solution. The system and method may be operated on a non-transitory computer-readable medium storing a plurality of instructions which when executed by one or more processors causes the one or more processors to perform the image registration method utilizing the enhanced phase correlation.

Abstract: A mid-wave infrared system provides high spatial and temporal resolution measurements of atmospheric temperatures and moisture fields using a constellation of low earth orbit satellites. The disclosed system is smaller, lighter, less complex, and requires less energy than existing systems, due to implementation of an infrared avalanche photodiode array detector that provides enhanced sensitivity with reduced cooling requirements, and an Offner spectrometer having a novel a refractive element inserted near the grating that reduces the size and power requirements of the spectrometer. Embodiments of the disclosed method include deploying a constellation of devices for cooperative infrared sensing of atmospheric phenomena at similar rates, lower cost, and much higher resolution compared to geosynchronous approaches. Some embodiments further include combined analysis of measurements obtained by the disclosed devices with complementary measurements made by other low-earth and high-earth orbital and/or ground-based devices.

Abstract: The system and method of improving the analysis of and implementation of a combat identification (CID) server system including providing correlation reports. There are at least two forms of correlation report, namely incident report and a summation report. The summation report has two types of totals, a summary total of all interrogations, and a breakdown of totals based on the Source JU. In one example, a correlated incident would be the combination of a Lock On or Mark Point with a Weapon Release, Disengage, or Attack.
