Communications subsystems for furture missions must be low-mass and enable equivalent if not great data return to the scientific community over the current X-band (8.4 GHz) links.
An overview is given of elements of the SIR (Shuttle Imaging Radar) project, covering the coming decade. The project is intended to develop the scientific basis and the required technology of the Earth Orbiting Satellite (EOS) Synthetic Aperture Radar (SAR). Plans are ongoing for a SIR-B reflight in 1987, a dual SIR-C flight in 1989 and a SIR-D flight in 1992 leading to an advanced multispectral multipolarization imaging sensor for flight on EOS in 1994. The conventional and distributed radar approaches are compared.
