IGS Radar 6 carries a synthetic aperture radar imaging payload capable of resolving objects on the ground day and night, regardless of weather conditions.

The spacecraft’s specifications, including its imaging performance, are kept secret by the Japanese government. But the government has acknowledged the satellite will join a fleet of Information Gathering Satellites operated by the Cabinet Satellite Intelligence Center, which reports directly to the Japanese government’s executive leadership.

The IGS Radar 6 satellite is Japan’s seventh radar reconnaissance satellite. The radar observers operate in tandem with electro-optical surveillance satellites, which offer better resolution, but only when their imaging targets have clear skies overhead.
