Application Notes
Today’s radar and electronic warfare (EW) systems face an increasingly cluttered spectral environment. As an example, the airwaves in an urban setting may include countless RF and microwave emitters—and therefore potential interferers—such as wireless communications infrastructure, wireless networking systems and civilian radars. Evaluating radar/EW hardware under a variety of highly realistic scenarios can help characterize system performance in the presence of multiple interference signals.
To test devices still in development, one possibility is to capture actual waveforms in the field and play them back in the lab environment. As a potentially more convenient alternative, a flexible software application such as Keysight Technologies, Inc. SystemVue can be used to create highly realistic multi-emitter test signals. These can be downloaded into a high-precision arbitrary waveform generator (AWG), which can play back complex signals for lab-based testing of a device under test (DUT).
