###ionospheric correction module parameters ###the values below are the default values used by the module ###remove # to set the parameters #maximum window size for filtering ionosphere phase: 200 #minimum window size for filtering ionosphere phase: 100 #maximum window size for filtering ionosphere azimuth shift: 150 #minimum window size for filtering ionosphere azimuth shift: 75 ###seperated islands or areas usually affect ionosphere estimation and it's better to mask them ###out. check ion/date1_date2/ion_cal/raw_no_projection.ion for areas to be masked out. ###The parameter is a 2-D list. Each element in the 2-D list is a four-element list: [firstLine, ###lastLine, firstColumn, lastColumn], with line/column numbers starting with 1. If one of the ###four elements is specified as -1, the program will use firstLine/lastLine/firstColumn/ ###lastColumn instead. For exmple, if you want to mask the following two areas out, you can ###specify a 2-D list like: ###[[100, 200, 100, 200],[1000, 1200, 500, 600]] #areas masked out in ionospheric phase estimation: None ###better NOT try changing the following two parameters, since they are related ###to the filtering parameters above #total number of azimuth looks in the ionosphere processing: 50 #total number of range looks in the ionosphere processing: 200 ###the above numbers should be integer multiples of the below numbers #number of azimuth looks at first stage for ionosphere phase unwrapping: 10 #number of range looks at first stage for ionosphere phase unwrapping: 40
