摘要

Scientists are one step closer to developing radar technology that will make more accurate measurements of space weather conditions possible. The technology, the Advanced Modular Incoherent Scatter Radar (AMSIR) system, was successfully field tested this month by SRI International, a Menlo Park, Calif .-based nonprofit research institute that conducts contract research and development for government agencies, businesses and foundations. The AMSIR project is made up of three separate systems, which scientists call "faces", each of which uses phased array technology to measure the density and movement of electrons and ions in the ionosphere, at distances between 80 kilometers and 1,000 kilometers up in the sky. Space weather is the term used to describe those conditions and processes in space that can have an effect on Earth's environment, including solar flares, coronal mass ejections from the sun, and changes and disturbances in the Earth's and interplanetary magnetic fields. Space weather can have detrimental effects such as disrupting power grids and causing interference with satellite communications.
