Design and Implementation of Rotating One-Dimensional uRAD Radar for Indoor Applications

Conventional radars generally work by propagating electromagnetic waves to detect objects in a narrow, forward-looking field of view. This constraint presents difficulties for applications that require broad object detection around the radar. To solve this, boosting radar capabilities through physical manipulation of the radar unit is preferable due to its simplicity and low cost. This research aims at the application of indoor one-dimensional radar technology by adding a mechanical system to overcome the limitations of the radar system. This study presents the design and implementation of an improved uRAD radar module that incorporates a mechanical system to rotate the antenna. This integration demonstrates the expansion of the operating scope of the radar by effectively extending the capabilities of radar in detecting objects beyond the constraints of one-dimensional operation. The experiment conducted shows that angular speed of 5 RPM and 10 RPM gives the accuracy of radar scanning of approximately 72% and 74%, respectively.
