Abstract: An improved target sighting device operable to converge on targets whose initial velocity has caused its image to move a significant fraction within the field of view during the period between detections utilizing less electrical circuitry and only one focal plane detector array. A detector array and associated signal processing system for incorporation within an electro-optical tracking system, the detector array comprising both fine track and coarse track detector elements wherein fine track and coarse track detector elements are further interconnected to hybrid fine track and coarse track signal processing algorithms. The resultant signals from the fine track and coarse track detections on the hybrid array will result in commands to gimbals about reflecting means or about a receiver telescope allowing the reflective means or receiver telescope means to be repositioned towards the target with greater accuracy.

Abstract: A fiber optic data distribution system is disclosed for distribution of the phase shift commands to an electronically steered antenna array. Novelties include the fan-out of a single bundle to multiple receptors, equalization of optical path for precise synchronization, the use of the RF active side of the antenna for data distribution, the use of the antenna radome as support structure for the fiber optics, and an optical reflector to divert light from the plane of the radome to the transmit/receive element.

Abstract: Disclosed is a unique probe and amplifier circuit for use with a digital height gauge or other measuring device. Fundamentally, the invention utilizes a probe tip operatively connected to the primary and secondary windings of an LVDT; the core of the LVDT being fixedly positioned between the windings. Deflection of the probe in either direction along the axis of the core results in an output signal from the LVDT, the amplitude of the signal being indicative of the magnitude of the deflection. The signal is translated into a varying DC level, the value of the DC level being linearly related to the deflection of the probe. The DC voltage is applied to an operational amplifier having selective feedback networks associated therewith which prescribe the gain of the amplifier and hence its subsequent effect upon a calibrated meter connected to the output thereof. The meter provides visual readings indicative of the deflection of the probe.
