EMISAR
Question 1
Into what general category of EOS does the instrument fall?
Fully polarimetric SAR
Question 2
What capture technology is used?
Side-scan radar
Question 3
Is the sensor active or passive?
Both passive (microwave radiometers) and active (radars) sensors
Question 4
At what wavelength(s) does the sensor function?
L-band (1.25 GHz, 24 cm wavelength) and C-band
Question 5
What resolution does the sensor have β temporal and spatial?
Temporal
N/A for airborne instruments
Spatial
1.5m x 1.5m sample spacing
Question 6
Is the sensor carried on an airborne or spaceborne platform? What is that platform β typically?
Airborne sensor. G-3 aircraft of the Royal Danish Air Force with pod and two XTI antennas (in front of the wing) The SAR is nominally operated at an altitude of 41,000 ft.
Question 7
Who developed/launched/manages the sensor?
Since 1989 Electromagnetics Institute and Technical University of Denmark
Question 8
Can data be purchased from service providers?
No
Question 9
What products are available?
Quad, dual or single transmit polarisation modes
1.5m or 0.75m sampling
Single- or Dual-frequency (L & C bands)
Single- and multi-pass interferometric imagery
Product List
Question 10
At which main application areas is the sensor aimed?
The land ice studies at DCRS aims at a better understanding of glacier and ice sheet as dynamics. The SAR++ project aims at improving design methods and technology for complex sensor systems involving wide bandwidth analog, digital, and antenna subsystems
List 2 specific projects, where they have been reported, their goals and their outcomes.
Greenland Arctic Shelf Ice And Climate Experiment
The research project is to relate the nature of ocean climate change over the last 2,000 years in part of the Arctic Ocean to the ways in which current rapid climate changes nature of the ice cover. In collaboration with AWI, DTU will use the satellite derived ice motion data to test and validate the ice velocities calculated by the large scale ice model
Greenland Sea Convection Mechanisms and their Climatic Implications.
βThe main objective of CONVECTION is to determine to what extent open ocean deep water production can be assessed by a combination of operational remote sensing, modeling, and a modest amount of field measurements. We seek to understand the physics underlying the convection process and how this process links with global climatic factors.β
