ERAVANT
Phase locked oscillators (PLO) utilize state-of-the-art planar circuits, three-terminal devices and dielectric resonator technology to generate high-quality microwave signals at lower frequencies. Frequency multipliers, amplifiers and filters are used to extend the low frequencies for higher frequency requirements. The standard offering covers the frequency range of 2 to 110 GHz and provides both internal and external reference options. The frequency stability and phase noise are dependent on the oscillator reference type.

Automotive radar sensors play a vital role in the current development of autonomous driving. Their ability to detect objects even under adverse conditions makes them indispensable for environment-sensing tasks in autonomous vehicles. As their functional operation must be validated in-place, a fully integrated test system is required. Radar Target Simulators (RTS) are capable of executing end-of-line, over-the-air validation tests by looping back a received and afterward modified radar signal and have been incorporated into existing Vehicle-in-the-Loop (ViL) test beds before. However, the currently available ViL test beds and the RTS systems that they consist of lack the ability to generate authentic radar echoes with respect to their complexity. The paper at hand reviews the current development stage of the research as well as commercial ViL and RTS systems. Furthermore, the concept and implementation of a new test setup for the rapid prototyping and validation of ADAS functions is presented. This represents the first-ever integrated radar validation test system to comprise multiple angle-resolved radar target channels, each capable of generating multiple radar echoes. A measurement campaign that supports this claim has been conducted.

ERAVANT
A Scalar Network Analyzer is a type of RF network analyzer that is used to measure only the amplitude properties of a DUT (Device Under Test). Unlike a Vector network Analyzer, it does not measure both amplitude and phase of the DUT.
