Layover separation in airborne single pass multi-baseline InSAR data based on compressive sensing

The analysis of urban areas by means of very high resolution SAR remote sensing always has to deal with effects caused by the side-looking imaging geometry. Recently, the separation of scatterers that collapsed in one layover affected resolution cell has been thoroughly investigated for multi-baseline InSAR configurations. While most of the time repeat pass data acquired by satellite SAR systems has been in the focus of research, this paper deals with airborne single pass multi-baseline data in the millimeter wave domain. Based on simulated data, the applicability of compressive sensing is investigated and adapted to a single pass system with four receiving channels
