Objectives

At the end of the module students are able to evaluate radar systems as well as approaches and methods of modern radar technology for location, navigation, and meteorology.

Description

1. Basics of Radar - Summary of radio wave propagation (refraction, scattering, range equation, Doppler effect) - Continuous wave (CW) Radar - Frequency modulated CW (FMCW) Radar - Pulse Radar - Pseudo-noise (PN) Radar - Monopulse Radar - Fundamental system parameters (resolution, accuracy, unambiguous range, duty cycle) 2. Components of Radar Systems - Basics of microwave electron tubes - Magnetron oscillator - Klystron amplifier - Solid-state amplifiers - Low-power Radar chip sets - Antennas and phased array techniques 3. Target Detection - Noise in Radar receivers - Phase noise in oscillators - Detection theory - Matched filter - Ambiguity function - Pulse compression - Clutter - Moving target indication (MTI) - PRF staggering - Constant false-alarm rate (CFAR) - Target tracking - RCS fluctuation 4. Synthetic Aperture Radar (SAR) - Working principle - Cross range resolution - Received signal properties - SAR data processing (range-Doppler, backpropagation) - SAR interferometry 5. Radar Meteorology - Polarimetric characterisation of wave propagation - Propagation in particle fields - Rainrate and water content estimation - Polarimetric classification

Prerequisites

Undergraduate Electrical Engineering: - Electrodynamics - Fourier analysis - Signals and systems High-Frequency Engineering: - Electromagnetic wave propagation - Antenna parameters Communications Engineering: - Modulation - Frequency conversion - Filtering

Teaching and learning methods

Teaching method: During the lectures students are instructed in a teacher-centered style. The tutorial lessons are held in a student- centered way. Learning method: In addition to the individual methods of the students consolidated knowledge is aspired by repeated lessons in exercises and tutorials.

Examination

The examination consists of a written examination of 90 min duration. In the written examination, students demonstrate by answering questions under time pressure and with limited helping material (formula summary, non-programmable pocket calculator) the theoretical knowledge of radar principles and algorithms. The final grade consists of the grade of the written exam (100%).
