deleteTrack

Delete track managed by adsbReceiver

Since R2021a

Syntax

deleted = deleteTrack(receiver,ID)

Description

deleted = deleteTrack(receiver,ID) deletes the track specified by ID in the ADS-B receiver object, receiver. You must update the ADS-B receiver object at least once before you are able to delete an ADS-B track.

Examples

Delete Track From adsbReceiver

Create an ADS-B receiver.

receiver = adsbReceiver;

Define ADS-B messages generated from transponder AAF123.

airbornePositionMessage = struct('ICAO','AAF123','Time', NaN,...
    'Latitude',70, 'Longitude',30,'Altitude',2000,...
    'Vnorth',250,'Veast',0,'ClimbRate',-1);

Call the receiver to generate tracks.

tracks = receiver(airbornePositionMessage,0)

tracks = 
  objectTrack with properties:

                     TrackID: 1
                    BranchID: 0
                 SourceIndex: 0
                  UpdateTime: 0

                 IsConfirmed: 1
                   IsCoasted: 0
              IsSelfReported: 1
            ObjectAttributes: [1×1 struct]

Delete the track.

tf = deleteTrack(receiver,1)

tf = logical
   1

Input Arguments

receiver — ADS-B receiver

adsbReceiver object

ADS-B receiver, specified as an adsbReceiver object.
