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. We include utilities for designing the Wilkenson power divider used to siphon off a sample of the transmit waveform for the homodyne receiver. We include design equations for using coffee cans for antennas, as well as the more broadband Linear Tapered Slot Antenna.

• 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)

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

pip install -e .

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

Fortran code:

cmake -B build

cmake --build build
