The present invention generally relates to a system and method for determining characteristics of traveling ionospheric disturbances (TIDs), and more particularly to a method and system for real time mapping of corresponding ionospheric perturbations, where in the case where the amplitude of each wave represents a height change, then the output field is truly a three dimensional representation of the height perturbations of an iso-ionic contour caused by the TIDs.

System and method for determining characteristics of traveling ionospheric disturbances

This invention relates generally to ionogram image processing, autoscaling and inversion systems and methods for ionospheric monitoring, modeling, and estimation of the same. One advantage of the present invention is to provide a system, e.g., a lightweight, low-power, and fully-autonomous ionospheric monitoring system that is able to provide fully processed and highly accurate ionosphere characterization in near real-time over a low data-rate satellite link.

Iterative ray-tracing for autoscaling of oblique ionograms

Through discrimination of the scattered signal polarization state, a lidar system measures a distance through semi-transparent media by the reception of single or multiple scattered signals from a scattering medium. Combined and overlapped single or multiple scattered light signals from the medium can be separated by exploiting varying polarization characteristics. This removes the traditional laser and detector pulse width limitations that determine the system's operational bandwidth, translating relative depth measurements into the conditions of two surface timing measurements and achieving sub-pulse width resolution.

Remote measurement of shallow depths in semi-transparent media

A method of calculating ionospheric scintillation includes calculating a motion-corrected perturbation of a GNSS radio signal received by a monitoring device deployed in an oceanic environment. The method includes calculating the σΦ using the high rate phase of the GNSS signal adjusted by removing the change in distance between the monitoring device and the GNSS satellite. The calculating the σΦ may further include passing the adjusted high rate phase through a high pass filter to remove a drift motion of the monitoring device. The method further includes calculating the Sthrough calculating a tilt angle between the antenna of the monitoring device with the GNSS satellite and adjusting the antenna gain through known gain pattern of the antenna. The wave height of the oceanic environment may be calculated by detrending the antenna height to remove low frequency motion when a high rate position of the monitoring device is calculated.
