Synthetic Aperture Radar on RADARSAT-1

Question 1

Into what general category of EOS does the instrument fall?

Synthetic Aperture Radar


Question 2

What capture technology is used?

Scanning Mechanism


Question 3

Is the sensor active or passive?

Active


Question 4

At what wavelength(s) does the sensor function?

C Band frequency 5.3ghz, wavelength 5.6cm


Question 5

What resolution does the sensor have – temporal and spatial?

Temporal

14 orbits per day

Spatial

Nominal resolution with various modes ranging from fine (8m) to scanSAR wide (100m)


Question 6

Is the sensor carried on an airborne or spaceborne platform? What is that platform – typically?

Spacebourne – Radarsat 1 satellite


Question 7

Who developed/launched/manages the sensor?

Canadian Space Agency (CSA)


Question 8

Can data be purchased from service providers?

Yes - Version 1 and version 2


Question 9

What products are available?

RADARSAT delivers seven standard data products reflecting the SAR mode options. These are available in three categories of geometrical fidelity - quick look, georeferenced, and geo-coded/ Quick look consists of the uncorrected SAR images. Georeferenced products are geometrically corrected to compensate for the Earth's curvature. RADARSAT's geocoded data products supply precise positional information to fit standard map projections.

Cartography, Agriculture, Military, planning, change detection


List 2 specific projects, where they have been reported, their goals and their outcomes.

Songliao plain agricultural development project – increase agricultural production, rural employment.

 

Search and rescue projects for military.
