Zusammenfassung

ESA's Earth Observation Projects Department in Noordwijk invites a university student to contribute to CHIME Enhanced Spatial Detection Capabilities. You will explore imaging spectroscopy and spatial enhancement in hyperspectral data, developing simulations and prototypes under expert guidance.

You will engage in end-to-end evaluation of spatial performance, instrument effects, and processing algorithms, reporting results to mission scientists and industrial teams.

Qualifikationen

• Must be a university student, preferably in final or second-to-last year of a Master's programme.
• Background in physics, applied mathematics, Earth observation, signal processing or aerospace engineering.
• Experience with Python, numerical modelling and statistical analysis.
• Familiarity with uncertainty propagation, sensitivity analysis or imaging spectroscopy is an asset.

Aufgaben

• Review the baseline pixel-binning approach and the telescope, spectrometer and pixel contributions to spatial performance.
• Develop a simulation and prototype processing algorithm.
• Evaluate sensitivity to noise, channel misregistration and differences in scene content between wavelengths.
• Quantify spatial improvement alongside any loss of radiometric accuracy or spectral fidelity.
• Document expected improvements and limitations of the proposed approach.
• Test the methods using representative mission scenarios and discuss results with mission scientists and industrial simulator teams.

Our team and mission

Within the Earth Observation Projects Department, the Copernicus Sentinel Expansion missions are currently under development. One of those missions is the CHIME (Copernicus Hyperspectral Imaging Mission for the Environment). CHIME plans to carry a unique visible to shortwave infrared spectrometer to provide routine hyperspectral observations to support new and enhanced services for sustainable agricultural and biodiversity management, as well as soil property characterisation.

You will join the CHIME project and work with the system engineering and mission-performance teams on end-to-end simulation, uncertainty propagation and the reliability of hyperspectral satellite data products.

Field(s) of activity for the internship

Topic of the internship: Enhanced spatial detection capabilities for Imaging spectrometer CHIME

Can imaging spectroscopy reveal materials smaller than a ground pixel, and can spatial enhancement improve their detection and quantification? You will investigate these questions for selected scientific applications using simulated or suitable reference observations.

What you will do:

• review the baseline pixel-binning approach and the telescope, spectrometer and pixel contributions to spatial performance;
• develop a simulation and prototype processing algorithm;
• evaluate sensitivity to noise, channel misregistration and differences in scene content between wavelengths;
• quantify spatial improvement alongside any loss of radiometric accuracy or spectral fidelity;
• document expected improvements and limitations of the proposed approach;
• test the methods using representative mission scenarios and discuss the results with mission scientists and industrial simulator teams.

Learning objectives

• assess how instrument modulation transfer function (MTF) affects CHIME’s spatial resolution;
• develop reproducible simulation and reconstruction methods to compare the baseline product with potential enhanced products;
• evaluate achievable spatial improvement and its sensitivity to noise, channel misregistration and spectral differences;
• communicate quantitative evidence to scientific, engineering and industrial specialists.

The principal outcome will be a tested software prototype that enables a feasibility assessment quantifying the achievable spatial improvement relative to the baseline CHIME product.
