multi_look_MLI

ANSI-C program: multi_look_MLI.c

NAME
multi_look_MLI - Multi-looking of real valued multi-look intensity image (MLI)

SYNOPSIS
multi_look_MLI <MLI_in> <MLI_in_par> <MLI_out> <MLI_out_par> <rlks> <azlks> [loff] [nlines] [scale]

<MLI_in> (input) multi_look intensity image (MLI) file (float)
<MLI_in_par> (input) MLI parameter file
<MLI_out> (output) multi-looked MLI image (float)
<MLI_out_par> (output) MLI parameter file for output MLI
<rlks> range looks for multi-looking
<azlks> azimuth looks for multi-looking
[loff] offset to starting line in the input data (default=0)
[nlines] number of input MLI lines to process (default=to end of file)
[scale] scale factor for output MLI (default=1.0)

EXAMPLE
multi_look_MLI 8560.mli 8560.mli.par 8560.mli3 8560.mli3.par 3 3

3x3 multi-looking of input MLI image.

multi_look_MLI 8059.grd 8059.grd.par 8059.grd5 8059.grd5.par 5 5 200 1000

5x5 multi-looking and section extraction for input ground-range (GRD) image.

DESCRIPTION
multi_look_MLI reads the real valued input MLI image, applies multi-looking to it, and writes out a new MLI image. A new parameter file to characterize the file dimension and geometry of the output MLI image is also created. The number of range and azimuth looks used in the multi-looking are specified on the command line and the offset to the starting line and number of input lines can be specified.

multi_look_MLI can also be used for the multi-looking of real valued images in ground-range geometry (GRD). The GRD parameter file has the same format as the SLC/MLI parameter files with the only difference that the range values corespond to ground-ranges and not to slant ranges.

multi_look_MLI takes into account line headers (as indicated in the MLI parameter file). The output multi-look intensity image has no file or line headers. The output MLI may be scaled using a command line parameter. A scale factor 1.e-06 is used to generate multi-look images for MSP processed radiometrically calibrated SLC images in short integer format.
