Eliminate Guesswork in RF Interference Analysis with the Automated Radio Measurement System (ARMS) Webinar


EMA is excited to announce a new capability that will eliminate the guesswork in RFI analysis. The Automated Radio Measurement System (ARMS) is a combination of off-the-shelf test equipment, custom filter banks, and LabVIEW software that is used to measure the broadband performance of both transmitters and receivers. Virtually every modern platform or system includes multiple radio frequency (RF) systems for navigation, communication, entertainment, sensing, and other applications. The criticality of the interference between these RF systems varies from nuisance problems to total loss of the platform. When the platform can be anything from a launch vehicle carrying a billion dollar payload to a passenger vehicle, there is no room for error.

The broadband transmitter emission and receiver susceptibility data necessary for accurate RFI simulations was previously unavailable. Analysts would gather as much information as they could from specification sheets and other sources. However, there were major shortcomings with this approach. In particular, specific frequencies and amplitudes for out-of-band performance was generally missing. These holes in the data resulted in either over-predicting interference problems due to conservative models or completely missing real interference problems. Both outcomes cost organizations money with inefficient testing and costly interference problems not found until the final stages of the design. With the ARMS capability, high-fidelity measured data can be used in RF system simulation tools to predict RFI with accuracy previously not possible. The ARMS capability saves organizations time and money. In this webinar, interference and mitigation of the interference will be demonstrated using data collected from the ARMS for commercial transmitters and receivers.



Matt Miller is a Principal RF Engineer II and one of the owners at Electro Magnetic Applications, Inc. where he leads a group providing analysis services for radio frequency interference (RFI), installed antenna performance, and radar signature prediction. Matt has 23 years of experience in electromagnetics. He worked for The Boeing Company from 1998-2001 as an Electromagnetic Effects (EME) engineer. From 2001-2005, Mr. Miller worked for SAIC-DEMACO as a Research Scientist. In 2005, Mr. Miller co-founded Delcross Technologies, LLC where he served as the President. Delcross developed commercial simulation tools for RF interference, installed antenna performance, and radar signature prediction including the EMIT software for RFI problems and the Savant/SBR+ solver for simulating the installed performance of antennas mounted to electrically large structures. In 2015, ANSYS Inc. acquired essentially all of the assets of Delcross Technologies. Matt joined EMA in 2017. He has worked on numerous RFI analysis projects for military and commercial customers for air, space, land, and sea platforms during his career.
