Radar and Remote Sensing for Environment

ABSTRACT

The course is aimed to introduce the students to the basics of radar and remote sensing for environment, also providing insights on the latest advances as well as envisaged future evolutions. The course is divided into three parts. The first part presents the principles and the fundamentals of radar technology for remote sensing. In the second part, modern radar systems for remote sensing of environment are presented. The third part focuses on specific applications of remote sensing for environmental monitoring. The course is organized according to a learning-by-doing modality in which several numerical exercises, exploiting SW programs, will complete the theoretical lessons.

 

COURSE CONTENT

Part 1: RADAR PRINCIPLES

  • Radar principles and objectives: passive/active radar; frequency spectrum; radar for detection, tracking, and imaging
  • Radar basics: radar equation; radar cross section (RCS) and clutter; pulse repetition frequency (PRF); resolution capabilities in range and the non-ambiguous range; Doppler effect; range and velocity ambiguities
  • Radar systems: monostatic, bistatic, and MIMO Radar
 

Part 2: RADAR AND REMOTE SENSING TECHNOLOGIES

  • Continuous waves (CW), frequency-modulated continuous-wave (FM-CW), and pulsed radar: principles, general architectures, and main applications
  • Synthetic Aperture Radar (SAR): SAR fundamentals; SAR acquisition geometries: conventional stripmap mode and spotlight mode; concepts of inverse SAR (ISAR) imaging; from image quality parameters to SAR specifications of HW and SW implementations
 

Part 3: REMOTE SENSING FOR ENVIRONMENTAL MONITORING

  • Basic criteria for radar instruments selection
  • Focus on weather radar: guidelines on how to collect, interpret and analyze environmental data according to World Meteorological Organization (WMO) standards and recommendations
  • Read and analyze base reflectivity images, base velocity images, wind maps, and precipitation images

 

TEACHING ACTIVITIES
