Putting FPGAs to Work in Software Radio Systems

Recently updated, this handbook reviews the latest FPGA technology and how it can be put to use in software radio systems. FPGAs offer significant advantages for implementing software radio functions such as digital downconverters and upconverters. These advantages include design flexibility, higher precision processing, lower power, and lower cost.

High-Speed, Real-Time Recording Systems

Recently updated, this handbook reviews some of the techniques and features that are widely desired in a high-speed, real-time recording system. Among others, these include the use of a non-proprietary file system, the use of a client-server architecture, and the presence of a user-friendly API (Application Programming Interface) for integrating the recorder into a larger system.

Performance Characteristics of Digital Frequency Discriminators

Digital frequency discriminators are key components of instantaneous frequency measurement (IFM) receiver systems as well as many other complex electronic warfare (EW) systems. However, to obtain optimum results it is essential to match DFD performance levels to a specific application. DFDs are integral components of IFM receiver systems; they may also be imbedded into a wide range of military systems such as radar warning receivers (RWRs), electronic countermeasures (ECM) systems, and electronic support measures (ESM) platforms, where they help provide instantaneous frequency measurement capability.

Unique Method for Orifice Production

To produce accurate, repeatable orifices, all the variables that might influence the Cd Value (Coefficient of Discharge) must be controlled during production. This includes the orifice hole length, edges, surface finishes, roundness and the elimination of all tool marks, burrs, ragged edges and irregularities. If any one of these areas is not perfectly managed, the orifice flow rates will vary from piece to piece thereby making it impossible to predict flow with any accuracy.

Protecting the Sky

This whitepaper provides insights into the use, specifications, and impact of Radio Controlled (RC) Unmanned Aerial Vehicles (commonly referred to as “drones”). UAVs intended for recreational use are increasingly being used for other (sometimes hostile) purposes. These include: observing/disturbing public events, spying in protected areas, smuggling contraband into prisons, endangering/threatening commercial air traffic, and entering restricted airspace. A technical approach for countering the threats posed by such drones is described, and includes: monitoring the spectrum for relevant signals, identification of frequency-agile RC signals, direction finding, and possible defensive countermeasures.

Successful Test Management For Systems Engineers

Designing a reliable test strategy requires broad, strategic thinking. The goal of verification is to ensure you release a best-quality system that meets customer expectations as documented in your early design concept and requirements gathering phases. To maximize the value of your test process, test your product objectives early.
