Radar receiver test system

20 January 2010 Test & Measurement

At productronica 2009, Rohde & Schwarz presented a configurable system solution for testing receivers in radar systems. Manufacturers and operators can use this application in development, production and service to simulate phase-coherent multichannel signals. The system generates simple modulated or unmodulated pulse sequences and can also be expanded to a maximum of 10 channels to create realistic scenarios.

The radar test system makes it possible to integrate even complex signal generation functionality into the development and production of radar systems. It provides high level and phase accuracy over a wide dynamic range (up to 118 dB) as well as high settling speed throughout the entire range (<1 μs/step at 50 dB). As a result, very fast, highly automated tests with complex sequences can be performed.

The system features an integrated R&S FSV signal and spectrum analyser that performs internal system calibration and provides accurate test results over a wide temperature range by recalibrating during startup or after temperature changes. In addition, the FSV analyses important parameters such as power or spurious of the transmitted radar pulses.

An R&S OSP switch and control platform as well as an R&S CompactTSVP serve as the interface to the radar receiver. The CompactTSVP PXI platform allows testing of the digital and analog signals of the DUT so that users can determine if the received and transmitted signals correspond. Furthermore, the graphical user interface on the PC makes it easy to set the signal parameters.
