EW Toolbox

Electronic warfare Python calculators and plotting tools for quick-look analysis.

Highlights

• Calculator library for:
  • FSPL and EIRP
  • J/S and burn-through range estimates
  • PRI, duty cycle, and unambiguous range
  • Coherent false-target delay-to-range spacing
  • Geometric radar horizon
  • Frequency-hop overlap probability
• Plotting:
  • J/S vs target range
  • RGPO delay profiles
• Interfaces:
  • CLI (python -m ew_toolbox.cli ...)
  • Tkinter GUI (python -m ew_toolbox.gui)

Models are educational approximations and should not be used for mission planning.

Install

python -m pip install numpy matplotlib
