The Effect of Whisper/Shout on Active BCAS Performance,

Abstract

When BCAS is operating in a high density environment the presence of synchronous garble will interfere with target detection. This report presents a simulation tool used to analyze the BCAS operation in a garble environment with several design variations. The chief BCAS enhancement evaluated was the technique known as whisper/shout. This technique can effectively reduce the garble problem when a BCAS aircraft operates in terminal airspace. In addition, the effectiveness of degarble capabilities is demonstrated in various airspace densities. A low cost general aviation CAS is evaluated with the same model and performs well in terminal airspace. It is concluded that in order to satisfy the draft U.S. National Aviation Standard for BCAS that a system must use full degarbling, whisper/shout and at least a 1-second update rate. (Author)
