IoSiS
IoSiS (Imaging of Satellites in Space) is an experimental radar operating in the X-band for imaging satellites in Low Earth Orbits (LEO).
The large Cassegrain antenna with a diameter of 9 m is a target tracking radar and simultaneously serves as a target illuminating radar for a (planned) swarm of passive, bistatic receiving antennas with a reflector diameter of 1.8 m each. The two already realized receive channels are located on the left and on the right side of the Cassegrain antenna. The transmit power is generated by a traveling wave tube (TWT). The transmitter’s bandwidth is about 4.4 GHz.
This experimental radar was used for practical demonstration of the possibility of using the ISAR method for tracking satellites.
