  1. Application Note: Design And Analysis Of A Proximity Fuse Antenna For An Air Defence Missile

    Air defense missiles typically require a proximity fuse, priming the missile warhead to detonate when the missile is close enough to the target. One of the ways that such a proximity fuse can be implemented is with a small radar that is used in short-range low power mode. The antenna for such a radar requires relatively good gain in the main lobe and side lobe levels (SLL) that are well below the main lobe level. This antenna is mounted conformal to the airframe of the missile and has a main lobe squint angle directed towards the nose of the missile. This article demonstrates how a design for an applicable antenna may be created and simulated in its operating environment with two popular software applications. By EM Software & Systems

  2. Integrated Circuits (ICs) And Component EMC Testing

    High performance electronic devices demand the use of multi-chip package (MCP), system-on-a-chip (SoC) technologies, and more complex circuits. Due to the increase in emerging technologies, it has become impossible to ignore the large amounts of parasitic emissions generated by such complex integrated circuits (IC’s). Those who produce IC products for demanding electromagnetic environments must also take precautionary measures to test and pass all regulatory EMI and safety requirements to achieve early time to market and profitability. This white paper explores these standards and safety requirements and offers guidance for ensuring that IC products meet them.

  3. Pulsed RF Spectrum And Signal Analysis

    The spectrum analyzer is used for the measurement of many characteristics of pulsed radar signals, including pulse width, occupied bandwidth, duty cycle, and peak average power. These devices are also capable of detection transmitter misfiring and frequency pulling effects. This white paper will discuss the operation of spectrum and signal analyzers, as well as explain the correct interpretations of their displayed pulse spectra.
