Rohde & Schwarz provides test and measurement solutions created to meet the most challenging requirements in aerospace and defence. The company's test instruments offer precise signal and phase noise analysis, clean signal generation and high-resolution time domain verification with unrivalled instrument performance, all of which is combined with a unique approach focusing on ease of use for engineers and developers.

The latest generations of multifunctional active electronically scanned arrays (AESA) radar systems have been developed as a response to the rapidly increasing complexity of electromagnetic environments and enhanced electronic warfare (EW) capabilities. These architectures bring new challenges, such as frequency and mode agility, as well as complex waveforms and pulse modulations in an often compact and fully-integrated radar system design. Hence, engineers seek the right tools to address the challenges, reduce risks, meet challenging time-to-market objectives and simplify the costly and time-consuming development and design processes.

Rohde & Schwarz provides a dedicated portfolio for radar and EW testing that focuses on bringing realistic scenarios - usually simulated in extensive field tests - to the lab. With this new approach, engineers and developers can achieve greater insight much earlier in the design and development phase. The R&S Pulse Sequencer software, for instance, used together with the company’s signal generators, provides an ideal solution for simulating angle of arrival (AoA) in the lab to verify the direction-finding performance of radar warning receivers. This setup eliminates the need for expensive field tests and is used to create complex simulations with static or moving emitters in a 3D scenario, providing a new level of realism, in any lab.

Furthermore, electronic attack and defence suites make extensive use of digital radio frequency memory (DRFM) jammers in order to deceive hostile radars and protect assets. Rohde & Schwarz offers a specialised product portfolio, including high-end signal and spectrum analysers as well as best-in-class phase noise testers, designed to address all challenges during the design phase of such smart jammers, but also for system performance validation and production.
