We will first present an overview of phased-array antenna fundamentals and basic Active Electronically Scanned Array (AESA) principles and challenges, and then we will explain how planar solutions can help with form-factor issues. We will also show how planar solutions at frequencies at or above X-band require increased integration, as well as highlighting some associated challenges.

Electronic Warfare Fundamentals Poster.Â This poster contains a radar warning receiver and DRFM based jammer block diagrams, a compare and contrast of Radar versus EW, basic equations, cross-eye jamming, modern jamming techniques, three areas of EW; common acronyms and the latest hardware and software for electronic warfare test and measurement.

Pulse signals are widespread in radar and other EW applications and must be accurately measured for manufacturing, design of countermeasures, and threat assessment. However, pulse measurements are an especially challenging area for signal analysis due to a combination of factors such as wide pulse bandwidth, pulses that are difficult to detect, and increasingly complex signal environments. This application note discusses the best tools for different types of pulse analysis, along with display and analysis techniques for various signals and measurement goals.
