High-Level Project Summary
SAR can provide extra information to analyze and respond to climate change, ecosystem loss, natural catastrophes, and other environmental phenomena that pose a threat to national and global security. Here are a few instances of how SAR might be utilized for such things:Agriculture: Surface roughness differences are a result of field plowing, soil tillage, and crop harvesting.Floods: Differences in surface reflection can help identify major flooding, minor flooding, metropolitan areas, and permanent bodies of water.Displacement of land. Differences in measurements over time can demonstrate sinking ground caused by the extraction of subterranean natural resources, for example.

Detailed Project Description
SAR can measure the distance between the sensor and the backscattered signal point on the Earth's surface . Slant range is the name given to this distance, which can be projected onto the ground to represent the ground range. The flight direction is referred to as along-track or azimuth direction, whereas the direction perpendicular to the flight path is referred to as across-track or range direction. The angle created between the antenna's pointing direction and the nadir is known as the view angle. The angle produced by the radar's beam midpoint and the normal to the local topography is known as the incidence angle. Both angles are occasionally used interchangeably, but only when the InSAR geometry is reduced and the Earth's curvature and local terrain are ignored. Climate change, ecosystem loss, natural disasters, and other environmental phenomena that represent a danger to national and global security can all be analyzed and responded to using SAR data. Here are a few examples of how SAR could be used for such purposes:
Floods: Differences in surface reflection can help identify major flooding, minor flooding, metropolitan areas, and permanent bodies of water.
Differences in measurements can reflect land displacements, such as sinking ground caused by the extraction of subterranean natural resources.
Climate change, ecosystem loss, natural disasters, and other environmental phenomena that represent a danger to national and global security can all be analyzed and responded to using SAR data. Here are a few examples of how SAR could be used for such purposes:
Agriculture: Field plowing, soil tillage, and crop harvesting all-cause variances in surface roughness.
Floods: Differences in surface reflection can help identify severe flooding, minor flooding, metropolitan areas, and permanent sources of water.
Differences in measurements can reflect land deformations, such as sinking ground caused by the extraction of underlying natural resources.
Space Agency Data
nasa was the first resource we used as it was the most reliable and had the most detailed information.
the Indian space agency was the second and last resource we used to get a different point of view and require more information.
Hackathon Journey
This hackathon was a great start for us since we haven’t participated in any competitions before, so it was a great opportunity to explore our capabilities and reach our maximum potential. We started as a group of high school friends with limited skills and no experience. We came a long way from those days.
Since the start, we were a bit shell-shocked as we saw how difficult those challenges were and we had no clue what to do. We spent days and nights researching and studying those challenges to choose the perfect one to suit our skills. So we choose this challenge because it tested the limits of our skills and pushed us way out of our comfort zones.
So we got down to doing this challenge and everything was going great but we faced some hiccups as we were filming we couldn’t find a decent location to film and we had sound issues, But we pressed through these problems and we met the challenge’s demands and we created a beautiful video.
