2. Product specifications
2.1. Outline of the product
The AIST ALOS/PALSAR InSAR products are the data processed by SAR imaging, precise coregistration for all scenes in the same frame, InSAR analysis, and unwrapping regarding
ALOS/PALSAR L1.0 whose polarizations are single (HH) and dual (HH, HV). The following software
was utilized for each process:➢Sigma-SAR

SAR Imaging, Precise Co-registration, InSAR analysis➢

SNAPHU

Unwrapping

The AIST ALOS/PALSAR InSAR product comprises 1) GeoTIFF files of SLC and InSAR images, 2)
text files containing metadata, and 3) SLC CEOS files conforming to the Japan Aerospace Exploration
Agency (JAXA) ALOS/PALSAR CEOS Level 1.1 format. Most GeoTIFF files are in the Cloud
Optimized GeoTIFF format.
Table 2-1 shows the main specifications of ALOS/PALSAR used in this InSAR analysis. The productoutline and the product type in each processing level are presented in Table 2-2 and Table 2-3,
respectively. Also, Table 2-4 presents the pixel spacing of the products.

Outline of the product
These data are complex data compressed in range direction andazimuth direction with zero doppler frequency. The magnitude andphase information in slant range coordinates are contained.
In the case of dual-polarization, the data are oversampled at the range
direction sampling frequency of single-polarization.
Also, the data are co-registered pixel by pixel to a single prime scene, acenter scene regarding spatial and temporal in the frame. Both orbital
and topographic fringes have been removed.

AIST ALOS/PALSAR InSAR Product Format Description

2.2. Differences from JAXA standard productThe differences between the AIST ALOS/PALSAR InSAR product (Level 1.3) and ALOS/PALSAR
product (JAXA standard product Level 1.1) are listed below.
i)Chirp replica signals before and after observations were not stored in ALOS/PALSAR level 1.0
of AIST. However, the following paper reports that the chirp rate is stable. The processing was
performed using the average value of the chirp rates.
PALSAR Radiometric and Geometric Calibration, M. Shimada, O. Isoguchi, T. Tadono, K. Isono,IEEE Transactions on Geoscience and Remote Sensing, Vol. 47, No.12, pp.3915-3932, Dec. 2009.

ii)

Satellite positions and velocities in the inertial coordinates are stored in ALOS/PALSAR level
1.0 of AIST. Then, the data converted to the fixed earth coordinates by taking into account only
the rotation of the Earth were utilized.

iii) Since the cut-out position of the scene of the AIST product is not defined according to the JAXA
standard product, the imaging ranges of the AIST product and the JAXA standard product inthe scene unit may be different.
iv) The AIST product consists of a dataset that is imaged at zero doppler frequency. In the case ofdual-polarization, the data are oversampled at the range direction sampling frequency of
single-polarization.
v)

The AIST product is co-registered to a single prime scene, a center scene regarding spatial andtemporal in the frame. Both orbital and topographic fringes for the single prime are removed.

2.4. Pixel value of GeoTIFF
Backscatter complex data 𝐼, 𝑄 (floating number) are stored in the resampled SLC. The formula
below calculates the backscattering coefficient (unit: dB).
𝜎 0 = 10 × log10 〈𝐼 2 + 𝑄 2 〉 + 𝐶𝐹 − 32.0
In the backscatter amplitude image, digital number 𝐷𝑁 (i.e., integer number) is stored. The valid
pixels have a value between 1 and 65535. Invalid pixels, such as that indicating an out-of-image range,
have 0. The backscattering coefficient (unit: dB) is calculated below.
𝜎 0 = 10 × log10 〈𝐷𝑁 2 〉 + 𝐶𝐹
These values are obtained with the ensemble average<>. The CF is a calibration factor included in
the metadata file.
The coherence image stores values from 0 to 255 and can be divided by 255 to make it coherence(0.0 to 1.0).
The images of the wrapped interferogram, unwrapped interferogram, elevation, and line-of-sightcontain real values, indicating the relevant numbers and whose units are radians for interferogramand meters for elevation. The line-of-sight is the vector from the satellite to the Earth’s surface.

3.4. CEOS file
The AIST ALOS/PALSAR InSAR CEOS file is a binary file conforming to the JAXA ALOS/PALSARCEOS Level 1.1 format.
The record structure of the CEOS file is shown in Table 3-7, and the format is presented in Table
3-9 through Table 3-21. The items whose definition differs from the JAXA CEOS format are marked
with an X in the “Different from JAXA definition” column. Simultaneously, the orange hatchingidentifies the repeated items.
As explained in section 2.2, because this product is co-registered to a single prime scene in theframe, the orbit data of the single prime scene is stored in the CEOS file. In addition, both orbital andtopographic fringes for the single prime scene are removed in SAR images. Even though these twopoints need to be noted, users can obtain the interferogram by taking only the phase difference
without major modifications to their existing SAR processing software since this product is a CEOS
file compliant with the JAXA format.
