Master's Thesis, 30 hp, ECTS: Orbit Information-Based Motion Compensation for Satellite-Based Passive Radar

Teknik, data och digitalt · Mjukvaru- och webbutveckling · Mjukvaruutveckling · Datavetenskap

I korthet

This Master's thesis project at Saab in Göteborg, Sweden, focuses on developing and comparing signal processing methods for satellite-based passive radar systems. The goal is to create a simulation model and investigate motion compensation techniques to improve target detection, evaluating sensitivity to orbit information errors and comparing different processing approaches.

Ansvarsområden

Create a simulation model for satellite, target, and receiver, including propagation path differences.
Generate reference and surveillance signals with controllable noise and uncertainty.
Model signal delay and Doppler shift for satellite and target trajectories.
Develop compensation methods for signal path length and Doppler shift changes.
Evaluate sensitivity to errors in orbit information.
Compare conventional range-Doppler processing with advanced approaches (e.g., window-based method).
Identify when motion compensation and geometric constraints improve detection performance.
Compare achievable performance with known orbit information versus signal-based estimation.
Investigate when external orbit information is necessary versus signal-based estimation.
Produce a reproducible simulation environment.
Compare detection probability, estimation accuracy, and computational cost.
