Solutions for Cost Savings in Creating Realistic Multi-Emitter Signal Scenarios Application Brief Introduction 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 hardware in the lab environment, one option is to capture actual waveforms in the field and play them back in the lab environment. Another option is to create highly realistic multi-emitter test signals. Better yet, combine both to provide flexible test spectrums consisting of both real world signals as well as simulated formats. Custom hardware and software to create these test signals can be costly. The design, development and testing of custom systems takes time, money and resources. This brief describes a commercial, off-the- shelf (COTS) solution for signal generation and analysis, and presents two example scenarios. Highlights include creation of multi-emitter test signals, the capture of real world signals, and combining these to create highly flexible test scenarios. 03 | Keysight | Solutions for Cost Savings in Creating Realistic Multi-Emitter Signal Scenarios - Application Brief Problem: Today's spectral environment becoming increasingly crowded with many sources of potential interferers Simulation sources have generally been world spectrum with simulated signals imagine combining radar, LTE and used in electronic systems level (ESL) makes the effort even more complex. 802.11ac wireless LAN (WLAN) signals. or electronic design automation (EDA) Achieving a common sample rate requires environments to design RF systems and In the past, a single emitter simulation the cumbersome process of finding circuits.
