| polarisationMode | Polarisation mode | acquisition | text/plain | Polarisation mode taken from codelist: ‘S’ (for single), ‘D’ (for dual), ‘T’ (for twin), ‘Q’ (for quad), ‘UNDEFINED’. |
| polarisationChannels | Polarisation channels | acquisition | text/plain | For radars designed to transmit either vertically polarised or horizontally polarised radiation. This means that the electric field of the wave is in a vertical plane or a horizontal plane. Likewise, the radar can receive either vertically or horizontally polarised radiation, and sometimes both. The planes of transmitted and received polarisation are designated by the letters H for Horizontal and V for Vertical. Thus the polarisation of a radar image can be HH, for horizontal transmit, horizontal receive, VV for vertical transmit, vertical receive, HV for horizontal transmit vertical receive, and vice versa (VH). Possible values: ‘HH’, ‘HV’, ‘VH’, ‘VV’, ‘HH, VV’, ‘HH, VH’, ‘HH, HV’, ‘VH, VV’, ‘VH, HV’, ‘VV, HV’, ‘VV, VH’, ‘HV, VH’, ‘HH, HV, VH, VV’, UNDEFINED. |

| platformShortName | Platform short name | platform | text/plain | The mission short name of the platform. This name is not a perfect identifier. |
| platformSerialIdentifier | Platform serial identifier | platform | text/plain | The platform serial identifier is the sequence number of the platform among the mission.

| platformNssdcid | Platform NSSDC identifier | platform | text/plain | Univocally identifies the platform. The exact syntax and lexical space of this identifier is defined by the World Data Center for Satellite Information (WDC-SI), which depends on the NASA’s National Space Science Data Center.
