425 Project SAR satellite [Thales Alenia Space]
The South Korean 425 Project radar satellites are the radar component of the 425 Project reconnaissance satellite project.
The high resolution SAR satellites are being developed by a consortium consisting of Korean Aerospace Industries (KAI) and Hanwha Systems Corp with Thales Alenia Space providing the SAR payload.
The Thales Alenia Space SAR payload uses a specialized 5-meter antenna folded as 24 petals that will open in space to form a prabolic dish. Additionally TAS provides also the platform elements, especially for Control Momentum Gyro and sensors, derived from their HE-R1000 product (High Efficiency Radar).
In 2022 the SpaceX Falcon-9 v1.2 (Block 5) was chosen as launch vehicles. It is unclear, if dedicated or shared launches will be used.
