Overview
ATSC 5340 is a graduate course that provides a foundational understanding of radar systems and their applications in atmospheric science. Students explore the physics of electromagnetic wave propagation, scattering, and attenuation, along with the design and function of radar instruments. The course covers the radar equation, Doppler radar principles, and the use of radar to observe clouds, precipitation, and atmospheric motion. Advanced topics include polarimetric radar techniques for identifying hydrometeor types and emerging technologies like phased-array radar and multi-sensor integration. Instruction combines lectures with practical exercises and data analysis. Students are assessed through homework, quizzes, and research presentations. By the end of the course, they are expected to interpret radar data from a physics-based perspective and understand both the capabilities and limitations of radar in atmospheric research.
The figure shows an example of radar signals, including the radar reflectivity and Doppler velocity under the hail condition, collected through the field trip as part of the radar meteorology class.
Objectives
This course is designed to provide a foundational understanding of radar meteorology, including the fundamentals of radar instrument design, scattering and radiative transfer theories at radar frequencies, Doppler principles, distributed targets of atmospheric scatterers, and the applications to radar remote sensing of clouds and precipitation. Graduate students will build solid theoretical and empirical bases for understanding how radar instruments work and what radar signals tell us about, and how useful radar measurements are in atmospheric science.
Goals
The goal of this course is for the students to understand the physical principles of radar theories and applications of radar remote sensing in atmospheric science and to be able to interpret radar-derived data in atmospheric science research from the physics perspective, through course lectures and practical exercises.
Student Learning Outcomes: The students will be able to
Understand the solid basis of the radar equation along with basic scattering, absorption, and radiative transfer processes relevant to radar and its application to radar remote sensing of cloud and precipitation.

Masa may be one of my favorite professors in the department. He is always so prepared for class, and despite not taking an official radar class himself does a great shot communicating everything. I thoroughly enjoyed this class, the structure of the class, and the coursework associated with the class.
I like the "Today's Radar" section—it is highly relevant to practical applications. The instructor explained complex radar principles clearly using illustrative diagrams, which made the content easy to understand. I believe this course will be very helpful for my research career. Thank you!
The lecture notes were crucial to my understanding of the lecture materials. I also really enjoyed the practical exercises and incorporating programming into the class. The hangar field trip was also really great!
The visuals, especially in the DFT notes, really helped a lot to understand the concepts. I also like the idea of doing the field trip earlier in the semester and then using the data from that for a practical exercise or etc.; I think that would be cool.
I felt that the homeworks worked positively in my understanding of the material, so I wouldn't mind seeing more regular homework assignments in a future course
Loved the field trip section in the radar applications! Would love to see even more of it.
I really liked the notes style- made for easy and accessible reference outside of class.
