Radar Image Parameters

The interface associated to this page is used to inform the radar image parameters, which will be converted from an external format to the GRIB format. The information presented here will be stored in the image file.


How to define the parameters for a Radar image:

  • click in the upper options button to inform the Prox Angle (degrees) - angle o in the following figure, Sl range distance (m) - distance from the sensor to the center of the illuminated area - or Sl range delay (mrseg) - time interval between the signal sent and the answer received. It is only required to inform one of these, because it will be used to execute the Slant to Ground conversion. The figure below shows the radar geometry;

  • click on Detect and select between Linear or Quadratic;
  • click on Range and select between Slant or Ground , in case of Ground image the values are not mandatory
  • type the Looks Number;
  • type the sensor's Height (m) in meters - the H measurement in the figure above;
  • give in Input Image the Number of bytes (8 or 16); in case the input image is an 8 bytes image it is required to inform if Swap was defined or not, and also the number of bytes (8 or 16) used in the Output Image;
  • click on Apply to confirm the defined parameters.

Converting images using IMPIMA.
