The spacecraft arrives at Venus in late July 1988 and begins its mapping mission which lasts for one Venus rotation or 243 days. This paper describes the VRM mission at its present state of design. The science objectives and project constraints are described. Key features of the spacecraft system and radar system are discussed.

The VISAR instrument takes advantage of radar hardware and interferometry advances since Magellan to enable improved mapping of the surface of Venus. VISAR is an X-band (3.8-cm wavelength), single pass interferometer that will acquire both imagery and topography, globally, for the Venusian surface.
Feb 1, 1987 · RADAR SYSTEM Radar is used for Venus mapping since it can penetrate the thick clouds of Venus. Real aperture radars can be used to provide images, but the along- track resolution is poor. The synthetic aperture radar, or SAR, takes advantage of spacecraft motion to create a synthetic aperture corresponding to an an- tenna length many times the real length.

The Venus radar mapper mission The Venus Radar Mapper (VRM) Mission, in 1988, will be the next NASA mission to Venus. This paper describes the mission as it is currently planned, showing how the design of the science payload, the spacecraft, and the mission satisfies the science objectives and requirements as well as other programmatic constraints.
A multimode (SAR, altimeter, radiometer) radar system was designed for the Venus Radar Mapper highly elliptical orbital geometry. The nominal mission lasts one full Venusian rotation of 243 days. The science objectives, mission constraints, radar system design, flight hardware, and ground processing methods are summarized. No Paper Link Available.
Venus Radar Mapper (VRM): Multimode radar system design The surface of Venus has remained a relative mystery because of the very dense atmosphere that is opaque to visible radiation and, thus, normal photographic techniques used to explore the other terrestrial objects in the solar system are useless. The atmosphere is, however, almost transparent to radar waves and images of the surface have ...
Jun 28, 2016 · Magellan spacecraft was a Planet Venus orbiter. It was as a high resolution radar mapping mission. It is also referred to as the Venus Radar Mapper.
