Keysight Technologies A Flexible Testbed to Evaluate Potential Co-Existence Issues Between Radar and Wireless Application Note Photo courtesy US Department of Defense Problem: Radar and wireless may interfere with each other Today's radar and electronic warfare (EW) equipment operate in increasingly cluttered RF and microwave spectral environments, with many potential interference issues. Spectral environments may consist of many different types of emitters including radar, wireless communications, wireless networking, and other potential interference sources. Co-existence between radar and wireless systems has the potential to be a significant issue. Investigating potential interference issues between complex wireless signals such as LTE (Long Term Evolution), WLAN (Wireless Local Area Network), WCDMA (Wide- band Code Division Multiplexing Access), and radar can be useful to ensure successful deployment. Testing these systems for co-existence prior to deployment may provide discernible benefits in terms of helping to identify potential co-existence issues earlier to reduce field testing time and potential re-work time. Finding and addressing problems in a lab environment is typically much less costly than trying to correct issues after deployment to the field.
