The range direction corresponds to the direction perpendicular to the flight direction of a radar system. It is also called across-track direction. One distinguishes between slant range, i.e. range in a radar geometry, and ground range, i.e. range projected onto the Earth's surface, and between near and far range (situated farther away from the sensor and showing shallower looking angle than in near range due to viewing geometry).
Explain and discuss what the range direction is
