AB Radar technology has evolved considerably in the last few decades. There are many areaswhere radar systems are applied, including air traffic control in airports, ocean surveillance, andresearch systems, to cite a few. Other types of sensors have recently appeared, which allow trackingsub-millimeter motion with high speed and accuracy rates. These millimeter-wave radars are givingrise to myriad new applications, from the recognition of the material close objects are made, to therecognition of hand gestures. They have also been recently used to identify how a person interactswith digital devices through the physical environment (Tangible User Interfaces, TUIs). In this case,the radar is used to detect the orientation, movement, or distance from the objects to the user’s handsor the digital device. This paper presents a thoughtful comparative analysis of different featureextraction techniques and classification strategies applied on a series of datasets that cover problemssuch as the identification of materials, element counting, or determining the orientation and distanceof objects to the sensor. The results outperform previous works using these datasets, especially whenthe accuracy was lowest, showing the benefits feature extraction techniques have on classificationperformance.
