Easy Testing Of Interferometric Direction Finders

The R&S RF Ports Alignment Software, together with the R&S SMW-K545 option, provides a standard and tailored solution for calibrating and aligning the amplitude, group delay, and phase between the RF ports of multiple coupled dual-path or single-path R&S SMW200A vector signal generators. 

Emulating Integrated Air Defense System

Doctrine, threat, tactics, availability, and readiness of equipment and people are just some of the variables considered in establishing an integrated air defense system (IADS) in and around an airfield. For this case study, D-TA Systems created a fictitious laydown in Syria of Russian and Syrian forces and used D-TA’s MRSE elements to make an open-air range of a realistic battle space.

System-Level LO Phase Noise Model For Phased Arrays With Distributed Phase-Locked Loops

By building upon known phase-locked loop modeling methods and an assessment of correlated vs. uncorrelated contributors, an approach to track distributed PLL contributions across frequency offsets is presented.

Generation Of Radar Signals For Multi-Antenna Receivers

Using a radar warning receiver (RWR) as a proxy for a generic EW receiver, this application note explains how the angle-of-arrival (AoA) capabilities of EW receivers can be tested with commercial off-the shelf (COTS) RF test equipment. Topics include the generation of scenarios, instrument setup, and setup calibration.

Power Supplies — What’s Better: Custom Or COTS?

When sourcing power supplies for military and commercial applications, system design engineers must choose between commercial off-the-shelf (COTS) or custom products. This article clarifies the misunderstandings of each, including delivery timelines, ease of integration, and real-world performance.

Creating Multi-Emitter Scenarios For Radar And EW Testing

This app note focuses on multi-emitter testing of radar and EW systems. Realistic testing of these systems depends on the generation of signals that accurately simulate multi-emitter environments consisting of thousands of emitters and millions of pulses per second, all arriving from multiple directions. 

Electronic Warfare, Drone Wars!

One of the numerous outcomes of military action has been the evolution of battle strategy and weaponry. This article addresses the use of drones as a protective countermeasure in the future of military applications.

Power Amplifiers Improve Communication Links

As a designer and manufacturer of RF amplifiers, we have always been confident in telling our customers that the more power output, the “better” your communications link. Just what is “better” needs defining, of course.

Addressing Filtering Challenges In Digital Broadband Receivers For EW

Electronic warfare (EW) receivers are being pushed to operate at higher bandwidths while simultaneously reducing size, weight, and power (SWaP). In this webinar, we break down how you can address these conflicting demands by diving into the building blocks of the receivers used in electronic warfare applications, with a focus on filtering needs and technologies.
