Development of Satellite Based Sensor for Improved Measurement and Validation of Ionospheric Parameters

Abstract

Having ionospheric electron density distributions as a function of height, latitude, longitude and time under different conditions is essential for scientific, technical and operational purposes. A satellitebased, swept-frequency, HF sounder can obtain electron density profiles on a global scale. We are developing a new-generation HF sounder that employs recent developments in technology, electronics and processing capabilities. It will provide global-scale electron density distributions, contours of fixed densities, maps of f0F2, hmax etc. It will allow us to map irregularities, estimation anomalous propagation and conditions for ducting, determine angles of arrival, etc. It will also be able to perform various plasma diagnostics and because of new flexibility, will be programmable from the ground to perform a variety of experiments in space. Need for such a system exists throughout the DoD and several civilian agencies.
