THE USE OF RADAR GATING DEVICES FOR REJECTION OF FALSE ATCRBS REPLIES.

Abstract

In addition to valid targets, the Air Traffic Control Radar Beacon System is susceptible to signal reflections that produce false signals. The effect is most noticeable at terminal facilities where airport buildings and other structures are close to the beacon antenna site. Some long range sites may also experience reflections to a lesser degree. The Agency program for implementation of side lobe suppression is directed towards a solution of the reflection problem. Technical tests have confirmed that SLS is effective and most reflections will be suppressed. Civil transponders have SLS capability today, but military transponders will not be fully updated until 1972. When operational precautions are taken, the interim use of special beacon gating devices that rely on primary radar signals is justified at some sites until SLS is implemented. (Author)
