Abstract
A transparent horizontal gradient freeze (HGF) furnace enables determining a crystallizing growth rate of an ingot by optically monitoring the rate at which a solid/liquid interface traverses across a charge of melted precursor material. The crystallization can be recorded for subsequent analysis, or a machine vision system can monitor and report the solid/liquid traversing rate in near real time, thereby enabling automated regulation of the growth rate to ensure uniform growth. Embodiments implement the disclosed furnace to produce crystalline or polycrystalline indium antimonide mixed with 1.8 wt % nickel antimonide (InSb:NiSb) at a growth rate specified according to required InSb:NiSb properties and a predetermined relationship between the growth rate and the properties of the NiSb needles formed in the ingot. Growth rates can be between 0.02 and 0.08 cm/hr for substantially single crystal ingots, and between 0.5 and 1.5 cm/hr for polycrystalline ingots. The InSb:NiSb can be doped with tellurium.

Techniques for direction finding and geolocation of a GPS spoofer. A methodology implementing the techniques according to an embodiment includes steering a beam in a direction selected from a search constellation and measuring a first signal power received through the steered beam. The method also includes steering a null in the selected direction and measuring a second signal power received through the steered null. The method further includes calculating a difference between the first signal power and the second signal power and estimating an angle of arrival (AOA) of the GPS spoofer signal as the selected direction if the calculated difference exceeds a threshold power value. In some such examples, the method includes accumulating signals having four similar estimated AOAs, associated with unique pseudo-random noise codes, and employing a GPS receiver to calculate a candidate position of a source of the GPS spoofer signals based on the accumulated signals.
