Tin Can Radar

Utilities for designing, building, and using a $35 Tin Can Radar, from the original 2006 prototype designed and built by Michael Hirsch and advised by Greg Charvat.

I include utilities for designing the Wilkenson power divider used to siphon off a sample of the transmit waveform for the homodyne receiver.

I include design equations for using coffee cans for antennas, as well as the more broadband Linear Tapered Slot Antenna.

If you need something more, start an issue or send a message.

  • FS2dBm.py Convert field strength in dBuV/m or uV/m to 50 ohm dBm
  • ToneFinder.py Simulate noisy sinusoids from target returns
  • Friis.py Compute Free Space Path Loss (dB)

Forward Model

A forward model of linear/non-linear FMCW chirp is provided in Python using an optional Fortran library for speed.

Build

  • Mac: brew install gcc
  • Linux: apt install gfortran
  • Windows: install gfortran

Install

pip install -e .

Matlab

Old scripts of some duplicity and perhaps not full correctness are in the matlab directory.

Optional

Fortran

optional

cd bin

cmake --build .
