L-BAND SYNTHETIC APERTURE RADAR SCENES
The Argentine SAOCOM® satellites have L-Band SAR technology. The signal they emit can penetrate soils, an ideal capability for measuring soil moisture.
L-Band SAR Radar Scenes: Acquisition Modes—
Acquisition Modes
Radar points to a given fixed direction while picks up a continuous band corresponding to narrower scannings and with more space resolution.
Radar changes its pointing along the trace to pick up several brands, covering a greater scanning width with less space resolution than in the StripMap case.
Radar changes its pointing along the trace to pick up a greater number of bands, covering a greater scanning width with less space resolution than in TOPSAR Narrow case.
Polarization Modes
The system issues and receives in the same linear polarization.
HH VV
The system issues in a linear polarization and receives in two linear polarizations simultaneously.
HH VV VV y VH
The system issues alternately in both linear polarization and simultaneously receives in them.
HH VV VV y VH
System transmits a circular polarization (right or left) and receives in two polarizations simultaneously.
right-H and right-V left-H and left-V

Frequently Asked Questions—
The form is for those interested in purchasing SAOCOM® Products to contact VENG and channel their needs.
As the SAOCOM® Satellite is a RADAR, the information it produces is independent of the cloud coverage. By working in L Band, the satellite can obtain information by penetrating the vegetation cover and soil, capturing moisture information. Among other products it can generate are:Ship Maps, Soil Moisture Maps, Forecast System of Wheat Spike Fusarium. The maximum resolution is 10mts, and the maximum revisit time is 16 days for ONE (1) Satellite and 8 days for TWO (2) Satellites, which can be reduced according to the requirements of the SAOCOM Product.
The maximum response time is 72 working hours. In case of urgency, please contact us by phone at +54 11 4340-5290, Monday to Friday from 9 am to 5 pm (Argentine local time UTC-3).
Customer service hours are Monday through Friday from 10 a.m. to 6 p.m. (Argentine local time).
On this site you will find the current price list. For products that are not included in it, please contact us. There are discounts for large volume orders or specific requirements, which are studied on a case-by-case basis with VENG’s commercial team.
