The purpose of this project was to design and implement a low cost and short range K band-continuous wave radar system prototype, which is able to measure distance and radial velocity for industrial applications. This is the final work for Master en Radar, Tecnologias, Equipos y Diseno de Sistemas master career, under the transfer of technology and knowledge agreement between The Kingdom of Spain and The Republic of Colombia. In next chapters there are described, step by step, all considerations for designing, manufacturing and implementing of the radar system, both in terms of hardware and software. The necessary tests and adjustments to get a functional prototype were performed. Attempting to minimize the cost of a potential product for industry, the prototype hardware has been implemented by using commercial elements (COTS: Commercial Off-The-Shelf), which are easy to get in the market. Referring to software, known tools in electronics development field were used, which facilitate the prototype capabilities. Measures of distance and radial velocity were obtained by using very few resources. Several future work lines were opened, which permit to improve the radar system capabilities. In addition to that, application fields were reviewed which are oriented to people or car detection in security topics, monitoring system for industries, smart home systems, UAVs control and other.
