NEWS 213/15 Invasion of radars Until recently, radar systems were a niche technology for the military, meteorology and air and sea navigation. Now they have conquered the wide-base market as indispensable components of automotive engineering. Wireless technologies Broadcast and media Radiomonitoring / radiolocation Easy characterization of DOCSIS 3.1 standard Virtual control centers complex smartphone frontends speeds up cable networks revolutionize air traffic control The NEWS app The R&S®News app for iPad, Android tablets and Amazon Kindle devices can be downloaded free of charge from the respective pro- vider’s app store. The app’s language can be set internally to English, German, French or Spanish. Besides the texts in the current print edition, all articles published in the last three years, sorted by topic, are accessible in seconds. The content is enriched by videos. Graphical signs mark which new arti- cles have appeared since the app was last opened, guiding you selec- tively to the innovations. You can find the app in the respective app stores, under the key words R&S News or Rohde & Schwarz. NEWS Published by Chief editor: Volker Bach, Rohde & Schwarz Rohde & Schwarz GmbH&Co.

Cover feature For an innovation to become a widely marketable product, all of its key components must reach a certain degree of maturity and be avail- able in sufficient volume at a reasonable cost. Without the fortunate convergence of the development of flat panel displays, electronic memories, batteries as well as sensor and communications tech- nologies, the smartphone could not have taken shape or begun its unprecedented victory march. There are parallels in the electroniza- tion of automobiles. Initially, only individual subsystems were elec- tronically upgraded, starting with the drivetrain. Now all components are networked via electronic control units and on-board computers thanks to miniaturization, digitization and more affordable high-perfor- mance electronics. New components are continuously being added to this complex meshwork as engineers seek to implement additional features for convenience and safety. As a result, formerly exotic tech- nologies such as radar are now being used on a massive scale – and even for security-critical tasks, which is why these technologies must meet the highest reliability requirements. But as is nearly always the case when it comes to high frequencies, the Rohde & Schwarz portfolio features the problem-solving T&M equipment – products such as the ARTS9510 automotive radar target simulator, which can eliminate the need for a large number of costly drive tests. Even the “full-fledged” radars that normally come to mind when this term is used are not left out. Special software analyzes their signals for all key criteria, making it possible to continue optimizing these systems in a focused manner. All articles on this topic can be found starting on page 30.
