Abstract

The current state shows synthetic aperture radar (SAR) with multimode and multipolarization capability and high performance in terms of image quality (e.g. COSMO-SkyMed, SPOTLIGHT: 1m resolution @ 10 km swath). A second generation of sensors (2009-2017) will include, among the main characteristics: the high resolution (sub-meter), the possibility of bistatic acquisition, the ability to identify moving targets (ATI / MTI). 

A next generation of sensors (> 2017), while maintaining the capacity already developed in previous generations, should include the possibility of: 

- multifrequency operations, 
- Flexibility (i.e. simultaneous acquisitions in different modes)
- ECCM capabilities using beam forming / nulling, 
- On-board processing 

These capabilities must necessarily be associated to a reduction of mass, volume and power consumption thus implying a larger integration and new technologies.
