Active microwave systems
Abstract
It is pointed out that the role of active microwave systems, often simply called radar, in remote sensing operations for geosciences has only recently been recognized. Surveys with radar carried by aircraft can be conducted with minimum flying time and on a schedule relatively independent of weather. The basic principles of radar are examined, taking into account the radar equation, the governing factors, basic elements of the radar system, radar resolution, range measurement, speed measurement, and angle measurement. A description of the radar scatterometer is presented and imaging radars are discussed.
