    Monopulse radars have played an important role in air and missile defense systems since the development of the monopulse technique in the late 1940s. This paper outlines the application of monopulse radars in Russian defense systems, starting with the Moscow ABM system and continuing in instrumentation and air defense radars now widely deployed in Russia and elsewhere View full abstract»

    This paper presents a new optical surface technology known as COUNTERFOIL. The COUNTERFOIL technology provides a means of covert information storage and is used as the basis for a range of security seals and labels. The technology has obtained Australian Government Endorsement (SCEC Endorsement) for use in high security applications. It provides a convenient, low cost means to determine authentici...

    The combination of microelectronic acceleration transducers and an RF telemetry link can provide a reliable means of measuring shaft vibrations of electric drives. Clear advantages include the possibility of installing the instrumentation into currently existing motor systems without any need to use flexible couplings or mounts. The proposed system covers frequencies up to several kilohertz and ca... View full abstract»

    Flywheel Energy Storage Systems represent an exciting alternative to traditional battery storage systems used to power satellites during periods of eclipse. The increasing demand for reliable communication and data access is driving explosive growth in the number of satellite systems being developed as well as their performance requirements. Power-on orbit is the key to this performance, and batte... View full abstract»

    Lockheed Martin Missiles and Space and Ultralife Batteries, Inc. are developing batteries for spacecraft and launchers based on Li-ion solid-polymer-electrolyte cell technology. These cells utilize a carbon anode, a manganese dioxide cathode and a solid polymer electrolyte. Electrode and electrolyte layers are thin and flexible. The electrode assembly is easily fabricated into thin, flat prismatic... View full abstract»

    A resonant switch-mode power supply for the microwave electrothermal thruster (MET) is presented in this paper. The converter is operated with soft-switching at high frequency and exhibits a high efficiency. The soft switching technique used in this converter and the current-source inductor at the input minimize the EMI noise. Electric isolation between input and output is achieved with a center-t...

    It is essential and desirable to get a high resolution echo in a radar image without using a large antenna. On scanning a radar antenna, the target's distribution is smoothed by the antenna beam and a smeared echo appears on the radar display. This paper describes three different types of beam compression radars: subsurface SAR; correlation array radar; and inversion processed radar. The experimen... View full abstract»
