NAME
phasefilt - phasefilt
DESCRIPTION
This program is part of GMTSAR.
- phasefilt [GMTSAR] - Apply adaptive non-linear phase filter
- USAGE:
phasefilt -imag imag.grd -real real.grd [-alpha alpha][-psize size][-amp1 amp1.grd -amp2 amp2.grd][-diff][-v]
- applies Goldstein adaptive filter to phase [output: filtphase.grd] or applies modified Goldstein adaptive filter to phase [output: filtphase.grd, corrfilt.grd]
-imag [required] GMT format file of imaginary component -real [required] GMT format file of real component -alpha exponent for filter - usually between 0.0 and 1.5 (0.0 should not filter).
- default: 0.5
- [Goldstein filter] (anything above 1.0 may be excessive)
- alpha < 0 will set alpha = (1 - coherence) [modified Goldstein]
-psize patch size for filtering. Must be power of two.
- default: 32
-amp1 GMT format file of amplitude image of image 1. Needed (and applies) modified filter. -amp2 GMT format file of amplitude image of image 2. Needed (and applies) modified filter. -diff Calculate difference between input phase and output phase. -complex_out Write out filtered real and imaginary (filtphase_real.grd and filtphase_imag.grd) -v Verbose. -debug Debug.
example: phasefilt -imag imag.grd -real real.grd -alpha 0.5
