The paper presents the development and implementation of a Digital Signal Processing algorithm for the Speed Indication Display with a 24 GHz continuous wave Doppler radar. The algorithm is based on a well-known zero-crossing algorithm and filtering. This paper is focused on implementing this algorithm into a widely used microcontroller, which is usually mounted on the Arduino Uno board. MATLAB/Simulink is used as a development environment to design filters, estimate the necessary word length and simulate the algorithm using fixed-point arithmetic before implementation into the microcontroller.
