| description | The trend in the conception of future spaceborne
radar remote sensing is clearly toward the use of digital beamforming
techniques. These systems will comprise multiple digital
channels, where the analog-to-digital converter is moved closer to
the antenna. This dispenses the need for analog beam steering
and by this the used of transmit/receive modules for phase and
amplitude control. Digital beam-forming will enable Synthetic
Aperture Radar (SAR) which overcomes the coverage and resolution
limitations applicable to state-of-the-art systems. On the
other hand, new antenna architectures, such as reflectors, already
implemented in communication satellites, are being considered for
SAR applications. An open question is the benefit of combining
digital beam-forming techniques with reflector antennas. The
paper answers this question by comparing the system architecture
and digital beam-forming requirements of a planar and a
reflector antenna SAR. Further elaboration yields the resulting
SAR performance of both systems. This paper considers multiple
novel aspects of digital beam-forming SAR system design, which
jointly flow into the presented system performance. |
