SpaceDucks's "What On Earth Is Synthetic Aperture Radar" project

High-Level Project Summary

Making a video that explains Synthetic Aperture Radar in a way that an non-expert person can understand.

Detailed Project Description

Very long antennas are needed to achieve high resolution in radars. Synthetic Aperture Radar technique provides high resolution with short antenna length. In order to obtain SAR images, measurements are at certain time intervals by flying the radar forward in the air taken along the desired aperture, and synthetic apertures are created with these data. One of the features of this radar is that it can be viewed over the clouds, regardless of day or night. SAR systems can detect moving objects as well as area imaging. The raw SAR data from the SAR radar is sent to the data preprocessing unit in the computer. Here, concussion compensation is performed on the raw data before the image is created. By processing these data with a computer, an artificial opening close to the physical opening is created. In Synthetic Aperture Radars, an image is created by broadcasting a continuous signal to the area to be imaged while moving in the direction of flight, and by processing the returning repercussion alone. A problem with the SAR technique is speckle noise, a problem unique to SAR images. The reason for this is that the raw data obtained is complex and this data is processed coherently. Different resarches have shown that the SAR technique has a great potential for soil moisture estimation, detection of mine and gas reserves, measurement of forest areas. As another usage area, beforehand it can be suggested to observe agriculture, forest and glacier areas in order to take precautionary measures against a problem that may occur in the future. It has also been seen to be used in military airfields. For example, for military usage, there is a aircraft named "SARPER" in Turkey's military airfield. Finally, three-dimensional terrain profiling is also possible with Interferometric SAR technology.

Space Agency Data

We did not use the data of the space agency. We used other datas.

Hackathon Journey

It was a very good experience, We learned new information and gained experience. . We learned how SAR technology works and its benefits . Thank you our teacher Ayşenur.
