RADAR TELEMETRY IN ASTRONAUTICS

Credits: 9

Learning objectives
The course deals with radar systems in remote sensing applications, either for Earth and Planetary observation, interferometric SAR, radar altimeters and radar sounders. SAR working principles, applications and sizing of the main system parameters.
Radar interferometry, baseline, altitude estimation, estimation accuracy, baseline decorrelation, time decorrelation. Radar altimetry: pulse limited geometry, Brown model, RX-TX block diagram, estimate of surface parameters, Cramer-Rao bounds, MLE and SMLE estimator. Spaceborn radars: Cassini, Marsis and Sharad.
