DIPDuino (Arduino) based Doppler radar research project.
I was not satisfied with K-LC6 trasceiver (http://www.rfbeam.ch/fileadmin/downloads/datasheets/Datasheet_K-LC6.pdf). I just can't get good detection range from it. This is why it was replaced with DF300 (http://www.agilsense.com/Speed-Detection-Borchure/26/59/page_content.html) from Agilisense.
New, more advanced radar board is ready. Working on implementation
of GUI interfaces and maybe speed simulator. See new pictures
First picture shows speed measurement (9 km/h) of the cooler fan of my 3D printer.
