Radio Plasma Imaging
To characterize plasma in the Earth's magnetosphere utilizing imaging in the radio frequency range.
Low-power radar which operates in the radio frequency bands which contain the plasma resonance frequencies characteristic of the Earth's magnetosphere (3 kHz to 3 MHz). The instrument consists of an electronics enclosure, four 250 m wire antennae with deployers (including switches and couplers), and a z-axis boom canister containing two 10 m lattice boom antennae and two preamplifiers. The measured plasma density varies from 5 particles/cm3 at the magnetopause to 100000 particles/cm3 in the ionosphere
