In a radar image, one can see only the energy that was reflected back towards the radar antenna. The radar moves along a flight path and the area illuminated by the radar, or footprint, is moved along the surface in a swath, building the image as it does so. [1] Digital radar images are composed of many dots.
RISAT-2B can operate in different modes including Very High Resolution Radar (VHRR) imaging modes of 1 × 0.5 m resolution and 0.5 × 0.3 m resolution. It is placed in an inclined orbit for better revisit rates over area of interest. Being a radar imaging satellite, RISAT-2B can image during day or night and in all weather conditions. [2]
Its major payload is an X-band (3.1 cm) radar sensor, with different modes of operation, which allows it to provide multiple imaging modes for recording images with different swath width, resolution and polarizations, see the figure for more details. In stripmap mode (spatial resolution of 3m), it needs 10 weeks to map global Earth's landmass.
Expect rainfall of 5 to 10 inches and local amounts up to 15 inches from Hurricane Helene.
RISAT-2B is placed in an inclined orbit for better revisit rates over area of interest. Being Radar Imaging satellite, it can image during day / night / all weather conditions. The Satellite will be utilized for high resolution spot imaging of locations of interest. [14] [15] Mass: 615 kg [16] Orbit: 557 km (circular) at inclination of 37° [16]
Weather radar in Norman, Oklahoma with rainshaft Weather (WF44) radar dish University of Oklahoma OU-PRIME C-band, polarimetric, weather radar during construction. Weather radar, also called weather surveillance radar (WSR) and Doppler weather radar, is a type of radar used to locate precipitation, calculate its motion, and estimate its type (rain, snow, hail etc.).
