“…The use of software defined radio (SDR) for research and development of radar applications has become attractive inasmuch as the flexibilization of the system increases by the facility in the change of (radio frequency) RF parameters such as frequency and gain [1], [2]. The integration of these two technologies is known as SDRadar and it has the advantage of being able to change the architecture of the radar by means of programming, while keeping the same hardware [3], [4]. SDRadar has the facility of modifying parameters of RF functioning through software and has allowed researchers and scholars to experiment different low-cost radar techniques with the help of free software such as GNU-radio.…”

This article presents a radar testbed for speed detection through micro-doppler effect in a controlled environment using software defined radio (SDR) technology. The target moves along a conveyor belt with software-controlled speed. The speed is detected by an SDR radar, and it is possible to compare it to an encoder-based sensor implemented on the testbed. The testbed as well as the SDR radar are reconfigurable and a (continuous wave) CW radar was implemented for the validation of the testbed; however, the testbed is not limited to this implementation. The testbed can be remotely operated because it includes the mechanism to move the target and control its velocity. The article shows the way in which the testbed was designed and implemented, the generation and processing of the radar signal using a limeSDR, and the validation of the radar measurements compared to the encoder-based speed sensor. The maximum speed obtained by the target in the testbed is 15.69cm/s. Results show a difference in the speed measured with the SDRadar of no more than 5% compared to the sensor measurememt. Results obtained allow characterizing the behavior of the SDR platform in the detection of low speeds.
