Hughes Network Systems announced its JUPITER™ 3 ultra-high-density satellite has successfully deployed its solar arrays and antennas, and the spacecraft has passed readiness testing by Maxar Space Systems.
Comtech announced a $20 million order from the company’s U.K.-based partners, Spectra Group, to service multiple COMET
orders already received and several expected follow-on orders from undisclosed customers in the NATO and European regions.
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.
For decades, spectrum analyzers have been used to develop and characterize radar and electronic (EW) warfare systems. However, traditional swept measurements are rapidly becoming insufficient because most modern radar systems are adaptive. Learn about methods for monitoring EW scenarios, identifying unwanted events in the transmitted waveform, and accurately measuring found signals.Ã?Â
This White Paper provides a view on radar waveforms for Aerospace and Defence and commercial radar systems. Waveforms such as pulse and pulse-Doppler signal, continuous wave and frequency shift keying waveforms are described. It also shows continuous waveform trends designed for specific needs and application differences of continuous wave radar compared to pulse radar systems.
The Defense Industry is facing many challenges. From shrinking budgets to Better Buying Power 2.0 to increased competition for program wins. And, for applications that rely on RF and microwave technologies, the supply base is highly fragmented resulting in increased costs and risks for prime contractors. Mercury is pioneering open architectures for RF/Microwave solutions and has implemented a concept around Advanced Microelectronics Centers (AMC) to provide the design, manufacturing and testing capabilities needed to deliver on key program needs. This whitepaper discusses why open architectures will be a game changer in RF/Microwave and what makes the AMCs unique and relevant.
This application note describes typical satellite applications that require power measurements and recommends power measurement solutions. It also explains how these solutions can help simplify your work, and improve accuracy, reliability and test coverage. Also covered are new sensor functions such as built-in Gamma and S-parameter corrections and real time measurement uncertainty calculations for improved accuracy.
This application note provides an overview of field testing radar systems and Line Replaceable Units (LRU) using high-performanceÃ?Â FieldFox combination analyzers having multiple measurement modes including a peak power analyzer, vector network analyzer, spectrum analyzer and vector voltmeter. This application note will show several measurement examples of pulsed and secondary radar signals and also reviews the basics ofÃ?Â monopulse radar.
