Is China preparing a SAR megaconstellation?
Ku band, 230kg, stackable flat panel

>Taijing 4-03 satellite is a high-resolution flat-panel SAR imaging satellite developed by Micro-Nano Starry Sky. It is my country's first commercial Ku-band phased array radar imaging satellite. The satellite weighs 230 kilograms, has a resolution of sub-meter level, and has multiple imaging modes such as bunching, striping, and scanning. The observation width in sliding mode can reach more than 10km. In addition, Micro-Nano Star Sky has designed and implemented a flat-panel satellite configuration for the first time. This configuration mode can realize multi-satellite stack launch, laying the foundation for large-scale satellite network launch, and its commercial technology level is at the leading level in the world. The satellite adopts an on-board intelligent processing system that can quickly generate images in orbit. For the field of ocean monitoring, it can quickly detect and identify sea and airport targets.

What is the global SAR situation today? How would Taijing 4 compare?
