  7. THE FALSE RADAR ECHOES DUE TO THE RADAR-MAST Many types of false radar echoes are observed on a ship-mounted radar scope, including side lobe echoes, interference echoes, second trace echoes, and others.
  8. The NWS office in Miami said at the time that strong temperature inversion caused the radar beam to bend toward the ground, where false echoes known as "anomalous propagation" were cgamtoggwortisuarnre.pifilkcentdubzewsramifornadivcale.infoinfo: Travis Fedschun.
