5 CONCLUSIONS 
To obtain high resolution digital images with a large swath width, the concept of staggered arrays is very useful. In this 
paper the theoretical background of image resolution with staggered arrays was presented. A quantitative approach for 
the resolution of an imaging system depends on the target structure and the resolution definition, which in our approach 
is related to the Rayleigh-criterion. The resolution was investigated for different target structures with non-staggered 
and staggered arrays. The results show an enhancement of the resolution with staggered arrays versus non-staggered 
ones by about a factor of two.
