Calculate the mean value of radar-grid samples using a polygon defined over geographical coordinates.

Parameters

[in]	radar_grid	Radar grid
[in]	input_dop	Doppler LUT associated with the radar grid
[in]	input_raster	Input raster
[out]	output_raster	Output raster
[in]	dem_raster	Input DEM raster
[in]	flag_apply_rtc	Apply radiometric terrain correction (RTC)
[in]	input_terrain_radiometry	Terrain radiometry of the input raster
[in]	output_terrain_radiometry	Output terrain radiometr
[in]	exponent	Exponent to be applied to the input data. The value 0 indicates that the the exponent is based on the data type of the input raster (1 for real and 2 for complex rasters).
[in]	geogrid_upsampling	Geogrid upsampling (in each direction)
[in]	rtc_min_value_db	Minimum value for the RTC area factor. Radar data with RTC area factor below this limit are ignored.
[in]	abs_cal_factor	Absolute calibration factor.
[in]	radar_grid_nlooks	Radar grid number of looks. This parameters determines the multilooking factor used to compute out_nlooks.
[out]	output_off_diag_terms	Output raster containing the off-diagonal terms of the covariance matrix.
[out]	output_radargrid_data	Radar-grid data multiplied by the weights that was used to compute the polygon average backscatter
[out]	output_rtc	Output RTC area factor (in slant-range).
[out]	output_weights	Polygon weights (level of intersection between the polygon with the radar grid).
[in]	interp_method	Data interpolation method
