PROJECT TITLE :

ATSC 3.0 Next Generation Digital TV Standard—An Overview and Preview of the Issue

ABSTRACT:

The Advanced Radar Geosynchronous Observation System is proposed to be a multiple-input–multiple-output synthetic aperture radar (SAR) system hosted on a swarm of minisatellites in quasi-geostationary orbits. The system is made of $N$ iso-frequency sensors, every of them transmitting and receiving the signals. The system would mix the continuous imaging capabilities of a geostationary SAR, gaining a issue $N^2$ in signal-to-noise ratio (SNR). The $64000 aperture would be achievable in $sim$40 min, enabling applications thus so much unseen, like monitoring quick deformations, landslides, and different applications for emergency and security. Still, the SNR of the long acquisition time would be conserved. The optimal design of the swarm is addressed, so as to trade resolution, coverage, and revisit time.
