|AIRSAR (airborne synthetic-aperture radar)
|NASA DC-8 aircraft
|AIRSAR POLSAR MLC products are available from NASA Jet Propulsion Laboratory
|Multi-look Complex, Standard Quad Polarization
SPW can read this data product without prior conversion. AIRSAR MLC data is distributed as a single file for each scene, for each frequency.
|Product-specific binary format
|The #### section of the file name is a product number that is unique to each data set. The last letter in the file name indicates the band frequency with which the image is captured (C band, L band, or P band).
|Nine 32R rasters and one array segment
The rasters are spatially coincident and represent the six independent elements of the symmetrized covariance matrix (C3r3c).
Three of these elements are real and correspond to one raster each. The other three elements are complex and correspond to two rasters each (representing the real and imaginary complex number components).
The rasters conform to SAR slant-range geometry.
The array segment contains an incident angle value (in degrees) for each range sample location.
Returned metadata for the data set level:
|The model name of the sensor that acquired the data.
|The sensor type.
|The data product type.
|The type of the matrix whose elements correspond to rasters in the data set.
|The SAR-related physical units of the pixel values in the returned rasters.
|The microwave frequency band in which the sensor operated during data acquisition.
|P, C, or L
|The set of <transmit, receive> polarization pairs that is represented by the data set.
|HH, HV, VV
|The number of looks processed in range and azimuth.
|A numeric value greater than 1.
Returned metadata for the channel level:
|The row and column position and number component (imaginary or real) of the matrix element to which the raster corresponds.
A real-valued matrix element has only a real component and is represented by one raster.
An imaginary-valued matrix element has both a real and an imaginary component and is represented by two rasters.
|Possible values for each raster: real_1_1, real_2_2 , real_3_3, real_1_2, imaginary_1_2, real_1_3, imaginary_1_3, real_2_3, imaginary_2_3
