Description

This ASAR Wave product is extracted from the combined SLC and Cross Spectra product ASA_WVI_1P generated from data collected when the instrument was in Wave Mode using the Cross Spectra methodology.

The product is meant for Meteo users. The spatial coverage is up to 20 spectra acquired every 100 km, with a minimum coverage of 5km x 5km.

The file size has a maximum of 0.2 Mbytes. Auxiliary data include Orbit state vector, Time correlation parameters, Wave Processing parameters ADS, Wave Geolocation ADS, SQ ADS.

This product provides a continuation of the ERS-SAR wave mode data.

Output: Wavelength range from 20 to 1000 m in 24 logarithmic steps.
