Design considerations on a sparse array antenna for Ka-band spaceborne SAR applications

This contribution addresses the problem of designing a sparse active array antenna for spaceborne SAR applications at Ka-band. The main driver for the design is limiting the recurring manufacturing costs associated to the number of active modules, while preserving main performance and insuring a certain level of industrial feasibility. A sparse...

Concept for Measuring and Compensating Array Deformation

Phased array antennas are increasingly used in modern radar systems. Such systems are very liable to distortion of the relative phases between the radiating elements. For airborne, spaceborne, and naval phased array systems, vibrations of the array structure are an important source of phase distortions. In this paper, a system concept will be...
