2. Simulation Datasets for the SAR
| Area | Tsukuba (The image center is located at 36°03'N and 140°06'E.) |
|---|---|
| Geographic Features | Including urban areas, forests, and paddy fields |
| Data Description | Airborne SAR (PI-SAR L-band) data Polarimetric scattering matrix data (HH,HV,VH,VV)(Calibrated and Uncalibrated) |
| Resolution | Azimuth: 0.6m Range: 2.4m slant range complex data |
| Size (Azimuth x Range) |
9084 x 2059 samples corresponding to 5km x 5km. 4ch BSQ format (HH,HV,VH,VV). Each sample is composed of Real (4 Bytes) and Imaginary (4 Bytes) parts. Data format is based on IEEE 32-bit Floating point expression with big-endian. |
NOTE: The form in which the data is supplied, either on-line transmission or media transfer, will depend on the data volume.
