    Abstract: The invention measures the frequency of a heterodyne laser radar (LADAR) system signal in the input cell of a focal plane array (FPA). Embodiments amplify the return signal, and drive it into a counter for a fixed period of time. The frequency is the number of counts divided by the count time. An example design amplifier amplifies the return of a single photon response of an avalanche photodiode with a gain of 100 into a digital signal level at a 200 MHz rate with only 84 μW, demonstrating the feasibility of the approach.

    Abstract: A high powered armor panel having the wideband embedded antenna for operation in severe environmental conditions. The armor panel comprises a driven bowtie dipole electrically coupled to at least one driven resistor, a parasitic bowtie dipole electrically coupled to at least one parasitic resistor, a composite structure which has the driven bowtie dipole and the parasitic bowtie dipole embedded therein, a heat sink supported on a first side of the composite structure for dissipating heat, and an armor layer supported on an opposite second first side of the composite structure. The heat sink supports the at least one driven resistor electrically coupled to the driven bowtie dipole and the at least one parasitic resistor electrically coupled to the parasitic bowtie dipole.
