S3TSR

S3TSR (Spanish Space Surveillance and Tracking Surveillance Radar) is operating in the L-Band surveillance radar for LEO Satellite Observation. The radar is installed at the Morón de la Frontera air base in the province of Seville (Spain) and its operation and maintenance is the responsibility of the COVE (Centro de Operaciones de Vigilancia Espacial del Ejército del Aire), a center through which Spain participates in the European SST consortium.

S3TSR uses a modular and scalable phased-array antennas in a close monostatic configuration, i.e. transmitter and receiver arrays are not at the same location but the distance between both facilities is very small (< 200 m) compared to the distance to the target. The radar can operate at more than 250 discrete frequencies spread over the ranging from 1 215 to 1 400 MHz. A number of transmitter blocks illuminate the covered space. The receiver site uses digital beamforming to generate 42 different Rx beams.

However, an exact angle measurement can only be determined with a network of different radar positions. The antennas used are not able to guarantee such a required angular accuracy. But the accuracy of the measured distance can be in the centimeter range. However, such a distance measured from two known locations can provide an exact position determination using multilateration.
