Problems producing interferograms with ALOS

Microwave Toolbox Interferometry
14

As mentioned on my post on 1st August on the thread: Interferogram from Alos palsar 1.1 data

Try to use lower coherence threshold and lower GCP tolerance.
I have used in the past these parameters:

Steps:

  1. Read master and slave
  2. Create Stack :
    extent: Master
    resampling type: Bicubic interpolation
    initial offset method: orbit
  3. Cross-correlation
    fineRegistrationOversampling: 16
    only GCPsonLand: false
    gcpTolerance: 0.25
    fineRegistrationWindowWidth: 32
    fineRegistrationWindowAccAzimuth: 16
    fineRegistrationAccRange: 16
    rowInterpFactor : 4
    InSAROptimixed: true
    ApplyFineRegistration: true
    fineRegistrationWindowHeight: 64
    columnInterpFactor: 4
    maxIteration: 10
    coarseRegistrationWindowHeigth: 128
    numGCPtoGenerate: 10000
    coherenceThreshold: 0.6
    coherenceRegistrationWindowWidth: 128
  4. Warp:
    interpolationMethod: Cubic convolution (6 points)
    warpPolynomialOrder: 1
    rmsthreshold: 0.05
  5. Interferogram:
    substractFlatEarthPhase: true
    srpPolynomialDegree: 8
    srpNumberPoints: 1001
    orbitDegree: 5

Please try with this and let us know. I hope this helps
Cheers
