R2026b

Release radar scan controller object

Since R2026b

Syntax

release(scanner)

Description

release(scanner) releases the radar scan controller object scanner, unlocking it so that properties can be modified.

Examples

Advance Scan Position and Update Properties

Create an electronic raster scan controller object with default values.

txScnr = radarScanController("Electronic","Raster")

txScnr = 
  ElectronicRasterScanner with properties:

      AzimuthLimits: [-90 90]
    ElevationLimits: [-5 5]
       ScanDuration: 1
          StepAngle: 1
            NumBars: 2
          Alignment: "Azimuth"
    DwellTimeSource: "Auto"
          ScanAngle: [-90 -5]
           ScanTime: 0

Advance the scan position to a time of 10 seconds and return the corresponding scan angle.

txAng = scan(txScnr,10)

txAng = 1×2

   -90    -5

Check to see if the current scan frame is complete.

isDone = isScanDone(txScnr)

isDone = logical
   0

Check to see if the object is locked.

t_f = isLocked(txScnr)

t_f = logical
   1

Release the scan controller object.

release(txScnr);

Update the scan duration to be 1/2 the current duration.

txScnr.ScanDuration = txScnr.ScanDuration/2

txScnr = 
  ElectronicRasterScanner with properties:

      AzimuthLimits: [-90 90]
    ElevationLimits: [-5 5]
       ScanDuration: 0.5000
          StepAngle: 1
            NumBars: 2
          Alignment: "Azimuth"
    DwellTimeSource: "Auto"
          ScanAngle: [-90 -5]
           ScanTime: 10
