Target class: satellite radar altimeter Context triple: [AltiKa radar altimeter, instanceOf, satellite radar altimeter]
-
A.
Ka-band radar altimeter
chosen
A Ka-band radar altimeter is a high-frequency radar instrument that measures precise altitude above terrain or sea surface by transmitting Ka-band microwave pulses and timing their return echoes.
-
B.
spaceborne radar sounder
A spaceborne radar sounder is an orbital remote sensing instrument that transmits radio waves toward a planetary body and records their echoes to probe and map subsurface structures and properties.
-
C.
scatterometer
A scatterometer is a remote sensing instrument that measures the reflection or scattering of microwave radar signals from surfaces, typically used to determine wind speed and direction over oceans or surface roughness on land.
-
D.
laser altimeter
A laser altimeter is a remote sensing instrument that measures the distance from the sensor to a surface by timing the round-trip travel of laser pulses, enabling precise elevation or topographic mapping.
-
E.
spaceborne synthetic aperture radar instrument
A spaceborne synthetic aperture radar instrument is an orbiting radar system that transmits microwave pulses and uses the motion of the spacecraft to synthesize a large antenna aperture, producing high-resolution images of Earth's surface regardless of weather or lighting conditions.
- F. None of above.
Provenance (1 batch)
The batch behind each pipeline step, in order, with when it ran. Timestamps are batch-level — stages were processed in waves, so the object chain (NER → NED1 → NEDg → NED2) reads in order, but predicate / elicitation batches can sit in a different wave.
