A quick look at the beginning at the meaning of SAR or Synthetic Aperture Radar, which means synthetic aperture radar, or according to its common meaning, radar imaging. Radar imaging techniques are used in many atmospheric applications, as they send their waves to the surface of the earth and are reflected in accurate two-dimensional images.

Then reprocessing the images to obtain high-resolution 3D images. SAR imaging techniques are used in combat aircraft, reconnaissance aircraft, drones, and airships, as well as satellites to create accurate images. Some Saudi projects dedicated to aircraft, radar detectors and sighting radars

Translation:

Advantages of radio imaging SAR The main advantage of SAR imaging devices is that monitoring is carried out regardless of weather or day or night lighting conditions that are not affected. In other words, SAR satellites can be used at night or with thick cloud cover over the area of interest and very accurate images can be drawn.

Translation:

SAR satellites are well suited for monitoring change such as landslides or rising water levels. - It can also estimate the number of cars that appeared in a parking lot during the night, or the number of containers that disappeared from the port.

Translation:

It can also be used successfully to monitor the condition of infrastructure, such as gas or oil pipelines, etc. The SAR satellite is well suited for maritime traffic monitoring as well. This is because ships or warships can easily be captured on the water.

Translation:

The SAR provides the ability to monitor large areas over short periods of time. For example, it takes about 30 seconds to collect images of an area of 100 x 50 km across a SAR, while it may take a few days to capture optical images of this small piece of land, with a suitable resolution.

https://twitter.com/x/status/1535615877952983040

Translation:

Dual frequency SAR satellite: Currently, all the SAR satellites in space are single-frequency satellites, meaning that they operate with only one wavelength. The competition for the priority of launching the first dual-frequency SAR satellite is between KACST and a consortium that brings together the US and Indian space agencies, NASA & ISRO, on their NISAR satellite.

Translation:

Introduction to the KACST project On 10/2015, the Space and Aviation Research Institute of King Abdulaziz City for Science and Technology began the last steps to reach their dream of international competition, which they set 25 years ago and worked hard to achieve. That date marks the beginning of the world's first dual-frequency SAR satellite project.

https://twitter.com/x/status/1535615893253783552

Translation:

Beginning of the project On 2015-10, KACST announced the beginning of the development of the dual-frequency SAR satellite as a highly advanced and unique satellite. An overview of the Saudi moon and some of its features in the upcoming tweets:

Translation:

The SAR payload is the first in the world to support Band L& X) satellite radar. - Supports StripMap mode and StripSAR mode to meet different needs and serve a lot of applications, such as high-resolution imaging and wide-area photography, coastal monitoring, monitoring changes specifically at points on the ground.

https://twitter.com/x/status/1535615905274683397

Translation:

The project includes 5 main phases: 1- Determining the main requirements of specifications, concepts and analyses. 2- Design and development. 3- Preliminary tests and development of prototypes. 4- Develop and test the engineering models that have been made. 5- Assembly and final exams.

You are welcome, Hamza. Good to have an Arab and Omani brother around.

Yes very much so, is the short answer.

“The primary advantage the radar sensors have, within the scope of carrying out observation, is the fact that the process may be carried out in a continuous manner. As opposed to the optical instruments, Synthetic Aperture Radar may carry out remote sensing activities regardless of the weather or lighting conditions.

In other words, SAR satellites may be used at night or with a thick cloud cover over the area of interest. The continuous nature of the observation provided by the ability to carry out this effort, regardless of the circumstances listed above, is of key importance, during each and every subsequent visit the satellite makes over the given area. Due to the reason above, SAR satellites are perfectly suited for monitoring change. Here one may refer to landslides or growth of water level in the flooded area. One may also estimate how many more cars appeared at a car park overnight, or how many containers disappeared from the given harbour. Satellite tools as such may also be successfully used to monitor the status of linear infrastructure, such as gas or oil pipelines.

SAR offers an ability to monitor vast areas over short periods of time. This is another of its major advantages. For instance, gathering imagery of an area which has dimensions of 100x50 kilometers takes around 30 seconds. Capturing optical imagery of such small piece of the Earth, with a proper resolution, may take up a few days.

SAR radar is well suited to monitor marine traffic too. This is because ships or warships can be easily picked up on the water, on the imagery as such.”​

For better overview, you can read this article which does a good job of explaining the concept of SAR satellites.

Very impressive.

 

[Corruptistan]

I have a question.

How does this development compare to regional ones in this regard? I imagine that only Israel is comparable if they have pursued this technology publicly.

Looks like this technology is purely the domain of very technologically advanced countries.

KSA is building their own.

NASA and ISRO have their own collaboration.

Translations are below every tweet in Arabic.

From what I recall, when posted it, there is a healthy race going on between them. It is for local Saudi Arabian/Arab consumption to see who they are up against.

Impressive nevertheless.

I have to admit that I don't know from where it will be launched once finished. I know that KSA has sent its own satellites into space from Kazakhstan (Baikonur Cosmodrome) on board Russia’s Soyuz-2 carrier rocket. As late as last year.
