Quantitative monitoring of surface movements on active landslides by multi-temporal, high-resolution X-Band SAR amplitude information: Preliminary results [PDF]
, 2016 Multi-temporal image cross-correlation is a method for tracking moving features and can there-fore be used for quantitative assessments of surface displacements. Accuracies of up to 1/8th of the original image geometric resolution can be achieved.

Validation for Ice Flow Velocity Variations of Shirase Glacier Derived From PALSAR-2 Offset Tracking
IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2022 We have shown that the flow velocity of Shirase Glacier can be estimated by applying the offset tracking method to the amplitude images derived from the phased array type L-band synthetic aperture radar type-2 (PALSAR-2) onboard the Advanced Land ...

Offset-free setpoint tracking using neural network controllers
, 2020 In this paper, we present a method to analyze local and global stability in offset-free setpoint tracking using neural network controllers and we provide ellipsoidal inner approximations of the corresponding region of attraction. We consider a feedback interconnection of a linear plant in connection with a neural network controller and an integrator ...

International Journal of Digital Earth, 2022 In this paper, the crack process of the A74 iceberg is carefully monitored in different aspects by using synthetic aperture radar (SAR) images. First, a offset tracking strategy is designed to retrieve the temporal evolution of the glacier velocity field.
