A radar emits electromagnetic radiation via a transmitter, and it has a directional antenna that measures the time of arrival of backscattered or reflected pulses of radiation from remote objects. The distance between the radar and object can be deduced using the speed of light.

What is term for the process of gathering information through images taken at a distance?
The term for gathering information through images taken at a distance is remote sensing. This technique involves using sensors to collect data from a target without physically touching it, often done from aircraft or satellites.
How do you look for water on other planets or moons?
We can look for it by using these tecniqes. •Seeing it in rocks (meteorites) •Seeing it gravitationally •Seeing it spectroscopically (remote sensing) •Seeing morphological features of it (remote sensing) •Seeing it (remote sensing)
What are the Values of remote sensing in gis?
Remote sensing provides valuable data for GIS by allowing for the collection of information from a distance using sensors on satellites or aircraft. This data can be used to create detailed maps, monitor changes in the environment, assess land cover and land use, and analyze spatial patterns. Remote sensing helps to enhance the accuracy, efficiency, and scope of GIS applications.
What are the four types of remote sensing?
The four types of remote sensing are passive remote sensing (detects natural radiation), active remote sensing (emits energy and measures its reflection), aerial photography (uses cameras on aircraft or satellites), and satellite imaging (capturing images from space using satellites).
Which groups was using remote-sensing technology before the 1960s?
the military
What is term for the process of gathering information image taken at a distance?
Remote sensing or perhaps spying.
What has the author Forrest Edward Dierberg written?
Forrest Edward Dierberg has written: 'Remote sensing for water quality monitoring in the Tennessee Valley' -- subject(s): Remote sensing, Reservoir sedimentation, Water quality 'Feasibility of using remote sensing platforms as an aid to water quality monitoring in the Tennessee Valley' -- subject(s): Water quality management, Remote sensing
Gathering information from a distance through images sound waves?
Remote sensing is the process of collecting data from a distance using satellite or aerial imagery, as well as sound waves like RADAR or SONAR. This technology allows us to gather information about the Earth's surface without physical contact. Remote sensing is widely used in various fields such as environmental monitoring, agriculture, and urban planning.
What is remote sensing and GIS?
Remote sensing is the use of technology to gather information at a distance (i.e. without making contact with the object). For example weather radars that detect incoming rain fronts at a distance are a form of remote sensing. GIS is an acronym for geographical information systems. These are methods of compiling, sorting, analysing and presenting the geographical distribution of differing types of data. For example you could plot time variations in rainfall data against differing geographical locations.
What is the science of taking measurements of planets from space?
The science of taking measurements of planets from space is known as remote sensing. Remote sensing involves using satellites, spacecraft, or telescopes to collect data from a distance without physically touching the object being observed. This can include measuring various properties of a planet such as its temperature, composition, topography, and atmospheric conditions.
How did remote sensing change the way geographic data were obtained?
Remote sensing allowed for the collection of geographic data without physically being on the ground. This technology enables the capture of information about the Earth's surface from a distance, using satellites, drones, or aircraft. Remote sensing has made it possible to gather data over large areas quickly and efficiently, revolutionizing the way geographic data are obtained.
Which type of remote-sensing system records electromagnetic radiation using a satellite-mounted sensor?
a compass
