Passive FM ionospheric radar

Functions used with data from MIT Haystack Intercepted Signals for Ionospheric Science radar.

data available from http://atlas.haystack.mit.edu/isis/fermi/events/

Usage

• PlotSCR plots Scatter to Clutter ratio of an HDF5 file.
• FMbesselSidebands theoretical sideband relative amplitude

These scripts assume Matlab, but could be adapted to include GNU Octave as well.

Download passive FM radar data

• Linux / Windows Subsystem for Linux: apt install wget
• Mac: brew install wget
