I am using the StereoSAR modual of ERDAS IMAGINE to construct a DEM. And it seems the result of "match" step determines the quality of the final DEM. However, my self-defined correlator always performd worse than the pre-defined correlator. I want to ask is there any principle about how to set the parameter of a match correlator?
Hi Xiaojie Zhang,
corelator value it take automatically in Erdas Imagine.
for highly terrain it should be high numbers in odd figure. Kindly also let us know, which dataset are you using.

I use TerraSAR-X stripmap data. the elevation of my study site ranges from about 1300m to 1800m.
Hi,
corelator to corelate the data in master/slave images using window size. If your z in between range, so you may increase correlation values.
