UPOS: HF-Radar Clutter

HF-Radar Clutter

Purpose:

The primary purpose of the HF-Radar Communication/Propagation software is to provide AFWA an ASCII data file containing information about the location of the Clutter Boundary and the capability to read this data file. The HF-Radar Communications/Propagation Clutter Boundary project provides a real-time determination of where high latitude ionospheric clutter is likely to be present. It determines the location using real-time data from the SuperDARN radars. The Clutter Boundary is determined directly from the measurement of convection velocity and backscattered power in the input radar data.

Inputs:

The software reads the clutter boundary data file

An ASCII file showing the location of the Heppner-Maynard Boundary with a color code to indicate the quality of the boundary determination.

File Format:
    Timestamp
    Number of Blocks
    Number of data records in the block; Number of items in each data record
    Header describing the three columns of data
    Units for each of the columns of data
    Data (Longitude, Latitude, Quality of Data)

Outputs:

Returns a pointer to the file structure containing the boundary information:
    Start and end times
    Number of segments
    Starting lon position of segment
    Starting lat position of segment
    Quality flag for segment
