Direction Finding techniques are widely used across the fields of radar, telecommunications, geolocation systems, sonar, among many others to estimate the reference position of the incoming signal source. For this, the implementation of antenna arrays is essential as it allows the use of more advanced techniques in signal processing called spatial spectrum estimation . This method of estimation is performed based on the antenna or sensor array response to the signal spatial parameters in every direction and estimate the location of the incoming signals. Algorithms have been developed for the purpose of spatial spectrum analysis, the most popular are MUSIC and ESPRIT algorithms and adaptations of these algorithms to different scenarios. This paper aims to use the MUSIC algorithm and attempt to develop a reliable testbed using Software Defined Radio (SDR) device called Universal Serial Radio Peripheral (USRP). In conclusion, design of this testbed is such that a USRP is used as a node device running the MUSIC algorithm, and synchronize it with another USRP node, running the same configuration to increase, not only to extend the number of antenna elements, but also provide a wide window of observation for the devices in order to create a triangulation process.
