Stripmap mode acquires data with an 80 km swath at 5 m by 5 m spatial resolution (single look). The ground swath is illuminated by a continuous sequence of pulses while the antenna beam is pointing to a fixed azimuth angle and an approximately fixed off-nadir angle. SM images have continuous along track image quality at an approximately constant incidence angle.
The following table shows the main characteristics of Stripmap mode.
Table 1: Characteristics of Stripmap mode
Stripmap imaging mode can operate with one of six predefined elevation beams, each at a different incidence angle. The table below shows the incidence and off-nadir angles for Stripmap beams.
The incidence angle is the angle between the incident SAR beam and the axis perpendicular to the local geodetic ground surface.
The off-nadir angle is the look angle between the satellite's nadir position and the SAR beam.
Table 2: Angles for Stripmap mode beams
Stripmap mode is used in exceptional cases only, to support emergency management actions.
