Testing commercial, military, and industrial electronic equipment for their performance in multiple-emitter environments can be challenging because of the complexity of the test signals needed. But as several examples show, it is possible to mate design simulation software with commercial-off-the-shelf (COTS) test gear, such as arbitrary waveform generators (AWGs), to create these complex test-signal scenarios. One example examines how radar and wideband-code-division-multiple-access (WCDMA) cellular communications signals can coexist, and how radar and IEEE 802.11ac wireless-local-area-network (WLAN) signals can share the same operating environment, and what happens when they do.
