Designing Antenna and Electronic Systems for Space and Airborne Applications

Across all industry sectors electronic systems such as antennas and sensors are becoming ubiquitous in support of wireless communication, sensing and power transfer. These are examples of the practical realization of the "Internet of Things". In the aerospace sector, such technologies are playing an increasingly important role in advanced technologies. For example, highly instrumented and connected aircraft are supporting condition based maintenance and health monitoring techniques. Remotely piloted systems are becoming more autonomous and delivering increasing amounts of intelligence, surveillance and reconnaissance data to support the warfighter. At the same time, the industry is expected to deliver these more advanced capabilities at lower cost, in a smaller and lighter footprint and with increased robustness, reliability and resilience.

Introduction into Theory of Direction Finding

Applications of direction finding While direction finding for navigation purposes (referred to as cooperative direction finding) is becoming less important due to the availability of satellite navigation systems, there is a growing requirement for determining the location of emitters as the mobility of communications equipment increases:

dB or not dB? Everything you ever wanted to know about decibels but were afraid to ask...

True or false: 30 dBm + 30 dBm = 60 dBm? Why does 1% work out to be -40 dB one time but then 0.1 dB or 0.05 dB the next time? These questions sometimes leave even experienced engineers scratching their heads. Decibels are found everywhere, including power levels, voltages, reflection coefficients, noise figures, field strengths and more. What is a decibel and how should we use it in our calculations? This Application Note is intended as a refresher on the subject of decibels.

Evolution of the Modern Receiver in a Crowded Spectrum Environment

The International Telecommunications Union Radiocommunications working group (ITU-R) outlines recommendations for the regulations and procedures for federal radio frequency management. This white paper takes a look at the evolution from the analog spectrum analyzer to the modern digital receiver in line with ITU-R Recommendations. It also gives some examples of the importance of the new architecture in today’s spectrum environment.
