Due to increased domestic air travel and threats to National security it is important that our Aviation RADAR systems function properly. The current airwaves are filled with many natural and artificial sources of interference. The natural background noise in RADAR bands is fairly constant, but there has been an increase in wireless communications traffic causing unintentional interference that may overflow into these bands besides the risk from intentional interference. These factors make it important to characterize your RADAR system and clearly understand all of the limitations. This article will demonstrate a simple test strategy to characterize Aviation RADAR system performance.
