    摘要: An array of individual and autonomous modules are deployed in a region to be surveilled. Each module, contained in an air dropable bomblet, includes a GPS system for determining the exact location of the deployed module. The module also includes an rf receiver and transmitter, as well as an atomic clock circuit for providing highly precise time and clocking signals, with operation of the module circuitry being governed by a control computer. The computers of the modules are individually programmed such that the modules of the array collectively operate as a distributed phased array antenna system, but without any hardwired interconnection between the modules. In another embodiment a single receiver is utilized and the apparatus operates on the frequency set of the GPS system.

    摘要: A broad band multimode seeker system for a missile includes a wide band phased array transmitter/receiver unit incorporating a wafer scale phased array device with a bandwidth of about 2 GHz to 35 GHz. A multimode intermediate frequency unit selectively generates radar and jamming waveforms and measures parameters of reflected radar and external emissions of RF energy. A guidance processor manages the front end assets for selective active or semiactive radar searching and tracking, and simultaneous searching for, tracking of, homing on, and applying a selection of electronic countermeasures to, multiple defensive radars. Confirmation of an assigned target is made through correlation of received RF signals with libraries of expected defensive system parameters and high resolution target profiles and preloaded target geographical coordinates.

    摘要: A coiled circuit device is produced by forming a circuit layer on a substrate. Optional insulator layers may be disposed above and below the circuit layer. The circuit layer, which may be memory, control, or other circuitry, is released from the substrate such that it coils into a dense, coiled device. A stressed coiling layer may be included which effects coiling when the circuit layer is released.

    摘要: An atomic clock of the type having a cell filled with an active vapor through which is projected a light beam. A detector of the projected light provides corresponding detector signals to a microprocessor. An rf frequency synthesizer provides a microwave signal to a microwave cavity adjacent the cell and also provides a clock standard output signal. The rf frequency synthesizer includes a fractional-N frequency synthesizer which compares signals from a voltage controlled crystal reference oscillator and a voltage controlled oscillator. The fractional-N frequency synthesizer is operable to provide an output control signal to precisely lock the voltage controlled oscillator microwave output signal with the voltage controlled crystal reference oscillator signal. The fractional-N frequency synthesizer also periodically causes a predetermined desired dither in the microwave signal.

    摘要: The invention provides frequency multiplier circuitry which may be used in the output section of high power microwave systems to efficiently provide higher output frequencies. Generally, one multiplier stage may be utilized to double the frequency of the input signal with several stages being cascaded to achieve even higher frequencies. The varactor diodes utilized in circuits of the invention are preferably constructed primarily of silicon carbide, which has many advantages when compared with current varactors constructed of GaAs or silicon. Some presently preferred embodiments utilize a four terminal varactor bridge instead of a single varactor diode. The invention also teaches several significant techniques for improving the bandwidth of the circuitry, thus allowing variation of the frequency of the input signal without significantly attenuating the output signal.

    摘要: An acousto-electric device provides a memory for a reference signal and provides for the convolution or correlation of input signals with the reference signal. The reference signal is transduced onto a piezoelectric surface to establish an electric field which determines the transfer and recombination of minority carriers across the p-n junction matrix of an adjacent semiconductor thereby creating a space-charge region in the semiconductor which is a spatial replication of the reference signal. The signal may be recovered in relation to the amplitude modulation of a carrier signal. For correlation or convolution of the reference signal with input signals, the input signals are provided to first or second terminals respectively and transduced onto the piezoelectric surface to produce electric fields which interact with the space-charge region of the stored reference signal to provide a product current whose integration comprises the correlation or convolution output.
