摘要： Techniques are provided for estimation of relative velocity between a receiver platform and a transmitter platform. A methodology implementing the techniques according to an embodiment includes measuring a first time of arrival, a first phase, and a frequency of a first radar pulse received from the transmitter platform. The method also includes measuring a second time of arrival and a second phase of a second radar pulse received from the transmitter platform. The method further includes calculating a relative velocity between the receiver platform and the transmitter platform based on a difference between the first time of arrival and the second time of arrival, a difference between the first phase and the second phase, and the frequency. The method further includes calculating an angle of arrival of the first and second received radar pulses based on a ratio of the calculated relative velocity to a velocity of the receiver platform.

摘要： An apparatus includes a lower plate, an upper plate above the lower plate, and a plurality of vias extending from the lower plate to the upper plate. The lower plate, the upper plate, and the plurality of vias include conductive material. A post including conductive material extends from the lower plate and towards the upper plate. An inner plate including conductive material is above and in contact with the post, where the post and the inner plate are separated from the upper plate by dielectric material. The plurality of vias are arranged to at least in part wrap around the post. A signal line extends between the lower and upper plates and at least in part wraps around the post, where the signal line extends through an opening between a first via and a second via of the plurality of vias. In an example, the apparatus is a resonator structure.

摘要： A transceiver unit includes an enclosure, a first input port, a second input port, a first output port, and a second output port. A radio frequency (RF) pass-through path is within the enclosure between the first input port and the first output port and includes a gain module. The RF pass-through path is configured to receive a first RF signal at the first input port and to transmit a second RF signal at the first output port. The gain module is configured to amplify the first RF signal to produce the second RF signal. The transceiver unit further includes a transceiver path within the enclosure between the second input port and the second output port, the transceiver path including a signal processor.

摘要： A system and method for utilizing a carbide-derived carbon (CDC) fiber in solid-phase micro extraction. Optically pumping the carbide-derived carbon (CDC) fiber, as compared to using thermal desorption, enhances performance of the system. CDC provides for a broad based sorbent that is insensitive to high humidity. Optical pumping may be done axially or radially on a modified gas chromatography needle. In some cases, staged, or pulsed, optical pumping is used to drive off solvent or other lower boiling compounds first and then the desorption of the remaining analytes is cleaner and the instrumentation is less likely to be overloaded.

摘要： A method of making GaP window slabs having largest dimensions of greater than 4 inches and GaAs IR window slabs having largest dimensions of greater than 8 inches, includes slicing and dicing at least one smaller GaAs or GaP single crystal boule, which can be a commercial boule, to form a plurality of rectangular slabs. The slabs are ground to have precisely perpendicular edges, which are polished to be ultra-flat and ultra-smooth, for example to a flatness of at least λ/10, and a roughness Ra of less than 10 nanometers. The slab edges are then aligned and fused via optical-contacting/bonding to create a large GaAs or GaP slab having negligible bond interface losses. A conductive, doped GaAs or GaP layer can be applied to the window for EMI shielding in a subsequent vacuum deposition step, followed by applying anti-reflection (AR) coatings to one or both of the slab faces.

摘要： An antenna assembly includes an antenna feed configured to receive a signal over a wide bandwidth, a ground plane, and an antenna element. The antenna element includes first and second conductive dipole arms each in planar alignment with a surface of the ground plane and adjacent to each other. The antenna assembly further includes a conductive wall (“H-wall”) in electrical communication with the ground plane and having an end adjacent to, and physically separate from, the second conductive dipole arm, where an axial length of the H-wall being orthogonal to the ground plane, and a resistive surface having an attenuation effect on the reflected signal from the ground plane.

摘要： A chaff dispensing system that is provided on an aircraft and includes a container, a dispensing assembly, a controller, and a volume of chaff material. The container has a first end, a second end, and a chamber that extends between the first and second ends, and the second end defines an ejection port. The dispensing assembly is operably engaged to the container. The controller is electrically connected to the dispensing assembly. The volume of chaff material is disposed inside the chamber of the container. The volume of chaff material is dispensed by the dispensing assembly operably through the controller in metered volumes of chaff material. In addition, a first volume of chaff material may be metered at a first time and a second volume chaff material may be metered at a second time in which the second volume of chaff material is different than the first volume of chaff material.

摘要： An antenna assembly includes a first dielectric material, a ground plane above the first dielectric material, and two or more patch antennas above the ground plane. In an example, the ground plane has a first aperture slot, and a second aperture slot that is non-intersecting with the first aperture slot. The antenna assembly further includes a second dielectric material separating the two or more patch antennas from the ground plane. In an example, the first dielectric material comprises a printed circuit board (PCB). In some examples, the ground plane and the two or more patch antennas are manufactured using additive manufacturing techniques (such as three-dimensional printing techniques), and in some such examples, the second dielectric material includes dielectric foam. For example, the dielectric foam supports the two or more patch antennas above the ground plane.
