Abstract :
This paper presents a new system idea for SAR, in which the key functions are software defined. This means they can be changed during a mission either by control of stored software or by downloading the new functions. The operation modes may be very flexible including side-looking and forward-looking modes. Multiple antennas arranged across track or along track are used for receive, depending on the application. The spatial resolution is achieved by phase comparison, Doppler and/or bandwidth compression. The system configuration becomes extremely simple and modular. Ground-based and airborne high resolution can be achieved. Digital beam forming on receive only can be implemented. These SAR sensors are also suitable for bistatic operation or for operation with transmitters of opportunity
