Abstract: A monopulse receiver, wherein a desired wide dynamic range is achieved for range gated monopulse sum and difference signals, is shown to incorporate: (a) a multiplexer for time-multiplexing such signals; (b) a first and a second receiver channel responsive to the time-multiplexed signals, each such channel having a dynamic range less than the desired wide dynamic range and greater than one-half the desired wide dynamic range, the gains in such channels being offset so that together such channels have the desired dynamic range; (c) a first and a second sampler and analog-to-digital converter, respectively, responsive to the signals out of the first and the second receiver channel, for producing digital words indicative of the amplitude of each component signal in the time-multiplexed signals; and (d) logic and control means for forming bytes from predetermined portions of each one of the digital words and for selecting the byte indicative of the amplitude of each component signal.

Abstract: The present invention relates to headwear and more particularly relates to a convertible survival hat which selectively covers multiple areas of the wearer's head, face and neck.

Abstract: Circuitry for controlling a phase-lock loop using a charge-pump phase detector is shown to comprise a phase detector network in combination with an operational amplifier connected to selected output signals from such network to produce a bipolar D.C. signal indicative of the phase difference between signals applied to such network, one of the signals being at a frequency half that of the other.

Abstract: An improved radar receiver is shown to include a plurality of intermediate frequency and video frequency amplifiers, each one of such amplifiers being arranged to process received signals within a different range of amplitudes so that the overall dynamic range of such receiver may be equivalent to the dynamic range of a conventional radar receiver with automatic gain control.

Abstract: Circuitry for compensating for the effects of changes in ambient temperature on an automatic gain control arrangement in a missile-borne receiver is shown to include an operational amplifier responsive only to the level of the output signal from an automatic gain detector and amplifier, such end being effected by using temperature sensitive elements in the input and feedback circuits of the operational amplifier.
