cpxlks

ANSI-C program: cpxlks.c

NAME
cpxlks - multilooking of complex image.

SYNOPSIS
cpxlks <CMPLX> <ML_CMPLX> <width> [rlks] [azlks] [start] [nlines] [r_start] [nsamp]

<CMPLX>	complex image file
<ML_CMPLX>	output multilook complex image
<width>	width of complex image
[rlks]	number of range looks (default=1)
[azlks]	number of azimuth looks (default=1)
[start]	starting line (default=1)
[nlines]	number of lines (default: 0=to end of file)
[r_start]	starting range (default=1)
[nsamp]	number of range samples to extract (default: 0=to end of line)

EXAMPLE
cpxlks 1352_1610.flt 1352_1610.flt3 2500 3 3 (generates multilook image (3 looks in range, 3 looks in azimuth) of entire input interferogram)

cpxlks 1352_1610.flt 1352_1610.section.flt 2500 1 1 1000 700 500 800 (extracts 700 lines of 800 range pixels (complex float i.e. 8 byte per pixel) starting at line 1000 and range pixel 500)

INSTALLATION
Source code cpxlks.c in ./src. For compilation adjust and use Makefile: Executable version cpxlks in . /bin

AVAILABILITY
Uses ISP type definition file typedef_ISP.h.

DESCRIPTION
cpxlks generates multilook image of complex input data file.

In addition to the multilooking cpxlks allows to select a sub-section of the input image.

OPTIONS
None.

SEE ALSO
typedef_ISP.h, reallks.

DIAGNOSTICS
All messages are generally self-explanatory.

NOTES
None.
