ECEN 5254 - Radar and Remote Sensing
3 credit hours
Prerequisites: ECEN 3400, Electromagnetic Fields and Waves, and Fourier Analysis.
Textbook: Notes and journal articles.
Goals: To provide the student with detailed knowledge about radar systems and their applications to remote sensing. After completing the class, students should be able to generate a paper design of an appropriate radar system for a given remote sensing application.
Topics:
- Wave propagation/scattering in different media: wave parameters, dispersion, reflection, refraction, attenuation, poynting vector.
- Radar system components:
- Transmitter/signal characteristics: pulsed, FM-CW, chirp, etc.
- Antenna: patterns, gain, impedance, phased arrays.
- Channel: role in system.
- Receiver: noise (system, antenna), baseband conversion, direct sampling, filtering, etc.
- Detection: linear, Doppler, etc.
- Radar equation: hard target, soft target, rough surface, etc.
- Signal processing: pulse-width, IPP, Nyquist, aliasing, range, Doppler, power, spectrum (peak, shift, width).
- Applications:
- Scattering: hard targets, Rayleigh, Mie, Bragg, rough surfaces.
- Hard targets: police radar, ground-penetrating radar
- Rayleigh: weather/precipitation radar
- Mie, thermal: lidar, incoherent scatter radar
- Bragg: wind profilers
- Rough surfaces: synthetic aperture
- Choice of Matlab, Mathematica, or IDL.
Laboratory Projects:
- None.
