I check my corner reflector time to time in EO browser and it is very useful. However, I have experienced two different results when I visualize the S1 IW mode products in two different days, one in the imagery day and one the days after. For example, there was a Satellite pass over my location yesterday and I visualized it in VV linear gamma and found bright pixels associated with my corner reflector. When I search and look at it again today, the number and location of the brighter pixels (corresponding to my CR location) are different. I cannot get the same results the day after. This is an example which showed two different results. I have got the screenshots but unfortunately cannot attach it here.
What can be the problem?
