University of California, Davis

Students Design Sophisticated Radar System

 

Company Profile

The University of California, Davis, is a public research university and land-grant university as well as one of the 10 campuses of the University of California system. Since its founding in 1962, the College of Engineering, in keeping with the UC Davis land-grant mission, focuses on finding technical solutions to some of our nation’s most challenging problems, while also preparing thousands of highly skilled engineers to join in this challenge.

The Design Challenge

Professor Xiaoguang “Leo” Liu teaches a senior project course, Design of RF/Microwave Systems in which students build small radars in the class. The course was created to satisfy the need for a senior project course for students who are interested in high-frequency electronic systems. The two-quarter long course emphasizes system-level design concepts and strives to provide a hands-on experience. As the course evolves, the projects start to encompass many facets of electrical engineering, including system engineering, antenna design, analog circuit design, embedded systems, and digital signal processing.

The first project option is the implementation of a frequency-modulated continuous-wave (FMCW) radar system that can perform range, Doppler, and synthetic aperture radar (SAR) measurements. In the first quarter, the students go through a series of structured labs to learn the basic system design concepts and acquire the necessary skills for putting together a high frequency system. In the second quarter, they propose and implement improvements to their radar system in terms of measurement accuracy, resolution, weight and power consumption. 

The Solution

All teams within the class were able to complete the competition and the best performing team had an excellent result. The scores are calculated roughly equal to accuracy, power, and weight of the radar, and the team whose device has the smallest number wins.
