Two dimensional image data of 256 gray scale levels (1 byte) that exhibit reflected echo strength of a sounder observation along a satellite orbit. The horizontal axis represents satellite flight direction, while the vertical axis is the distance from the satellite, namely the depth in the lunar interior below the lunar surface. Large echo intensities indicate the lunar surface and discontinuities below the lunar surface. This data product corresponds to B-scan image, which can be produced by arranging A-scope images along a satellite orbit. An A-scope image can be generated by FFT processing of a received raw signal of Sounder operation. The spatial resolution along a satellite orbit is 75m. The spatial resolution in the range direction (depth direction) is about 75m. One file is for a region of about 1000 km (10 minutes observation) along a satellite orbit. |

This data product corresponds to B-scan image, which can be produced by arranging A-scope images along a satellite orbit. An A-scope image can be generated by FFT processing of a received raw signal of Sounder operation. The spatial resolution along a satellite orbit is 750m (SDR_W and SDR_S modes) or 600m (SDR_A mode). In cases of SDR_W and SDR_S modes, 10 pulses are averaged to reduce the spatial resolution in the along-track direction. The spatial resolution in the range direction (depth direction) is original 75m. One file is for a region of about 1000km (10 minutes observation) along a satellite orbit. |

Derived Data - Subsurface geologic structure interpretation map |
An interpretation map showing subsurface geologic structures derived from sounder low-resolution subsurface cross sections, also referring to data products to be provided by the other instruments. Subsurface discontinuities along with their displacements (if any) will be drawn. The lithology and formation age might be described for strata between discontinuities if known. This data product will be generated for only limited regions, because this data indicate interpretation of subsurface geologic structures. |
