Radar systems help drive much of the modern world, especially unmanned vehicles, on land, in the air, and even in space. Measuring distance accurately and robustly is incredibly important for allowing autonomous systems to sense their environment. Radar is one of the most reliable ways to measure distance, as it is not impaired by poor visual conditions (e.g. fog, rain, or bright lights), unlike lidar.
Frequency Modulated Continuous Wave (FMCW) radar, can be much more robust than traditional radar. While other systems rely on measuring a signal's change in time (which relies on very precise clocking & is susceptible to noise), FMCW measures a shift in frequency to detect an object's distance (far easier to achieve in real-world environments).
Our project will demonstrate a FMCW radar system on a Printed Circuit Board (PCB), with transmitted frequencies ranging from 1 to 2 GHz, with target resolution of 1 centimeter at 1.0 meter. The data will be fed into a computer for processing & visualization.
