ASEN 5168: Remote Sensing Instrumentation Design
Description
Surveys the principles of remote-sensing system design. Emphasis is placed on satellite-borne visible and near-infrared instruments. Topics: Satellite remote-sensing techniques, properties of the electromagnetic radiation, visible and near-infrared detectors, imaging systems, radiometry, instrument-spacecraft integration, and current and future remote-sensing systems.
Outline
- Overview
- Background, Examples of Past, Current and Future Instruments, Intro to Radiative Transfer
- More RadiativeTransfer Basics - focus more on specifics of optical and microwave radiation
- Systems Engineering: Requirements Analysis and Functional Design
- Systems Engineering: Design Optimization and Trade Studies
- Systems Engineering: Development, Integration and Test
- Optical Remote Sensing Instrumentation
- Optics Overview (Snell's law, reflection, refraction, lenses, focal length)
- Optical Design (mirrors, telescopes, optimizing focal length, aperture, field of view, etc. within constraints)
- Detectors: Overview (photoelectric, semiconductor, CCD)
- Detectors: Technological Challenges (real world examples of some common issues)
- Spectral Response (dichroics, filters, hyperspectral approaches),
- Electronics: Overview (focal planes, signal integration, compression)
- Electronics: Technological Challenges (more real world examples)
- Instrument Characterization and Calibration
- Instrument-to-Spacecraft Considerations (data transfer, power, mass, volumn, jitter),
- Design Example: MODIS
- Passive microwave Remote Sensing Instrumentation
- Differences Between Optical and Microwave Remote Sensing
- Antennas: Overview (differences and similarities with telescopes)
- Antennas: Design (optimization of antenna size and other parameters within constraints)
- Antennas: Technological Challenges (more real world examples)
- Antenna Pattern Correction
- Synthetic Apertures (as an example of how to overcome the size constraint problem)
- Multi-Sensor Remote Sensing (motivation for combining visible/infrared and microwave, sensor-to-sensor and spacecraft-to-spacecraft calibration/collocation issues)
- Design Example: SSM/I
- Active Microwave (Radar) Remote Sensing instrumentation
- Differences Between Passive and Active Microwave Remote Sensing
- Radar Design Optimization
