Remote sensing Definition and 15 Threads

Hi I was watching Generally - you can activate use a strong magnetic field on ground, perturb it, and the pick the signal up with a satellite. The result would be in 60 to 1000 MHz ( VHF Television ) by a satellite. But the post also says, that US army is using it to detect burried weapons...

hi all, This isn't simply physics but is very much related. I'm trying to make an infrared thermometer or some means of remote temperature measurements for temperatures from 0 degree C to around 400 degree C I started with looking up low cost silicon photo diodes / photo transistors e.g. on...

hey guys, I'm in a serious pickle, its finals week and I have a final for remote sensing coming up. I was recently hit by a car riding my bike to school and have struggled studying for this final. I feel like I have a grasp on the main concepts of the course but am reaching out to any experts...

Hi all, I don't know if I'm on the right forum to ask this, but maybe somebody knows anything about brightness temperatures measured by remote sensing devices. In a paper that I read "Atmospheric corrections for retrieving ground brightness temperature at commonly-used passive microwave...

My question stems from the Cosmic-1 satellites using single antennas for radio occultation and the cosmic-2 sats that will use a phased array antenna. I've done a fair amount of research in regards to the phased array antenna. Overall it seems to improve the signal to noise ratio when making...

I dropped out of physics in college and have several career choices now for the near future being all vocational. In the far future I want to end up in planetary sciences again. So, I'll want to work again with planetesimals, dwarf planets, evolution of planets, their geology, and astrobiology...

Homework Statement A geostationary satellite is located at 0'N 0'E (degrees), 36000 km above a spherical Earth with radius R(earth) = 6370 km. To scan the fieldof view, the satellite rotates around its own axis(oriented parallel to the Earth's rotation axis). It records one (constant latitude)...

Homework Statement A satellite infrared radiometer (λ = 10 micrometer, footprint size 5x5 km) is observing a region of mixed open water and ice covered sea surface, where the temperature of the open water is -1 degree celsius and that of the sea ice -7 degree celsius. In the infrared, sea ice...

Greetings everybody. I have been tasked with doing an small (12 pages) study about measuring the thermal signatureof a city and the surrounding landscape with a satellite. I'm afraid I haven't touched the subject very deeply, and I would thank anybody who would point me to some books which...

Homework Statement You have a geostationary satellite (location 0◦N 0◦E, 36000 km above geoid). Assume the Earth to be spherical with a radius of REarth = 6372km When observing a region centered at 60◦N 0◦E: What is the incidence angle of the satellite’s line of sight (at pixel center...

Am a Physics undergraduate student; I need project topics based on Geophysics or Remote Sensing or Electronics

A thread on another forum got me thinking, you know in Star Trek they're somehow usually able to scan a ship or a planet for lifeforms? I wonder, what way could you realistically scan for a life remotely like that?

I said in an earlier thread that I was interested in embedded sensing as a career. It turns out that remote sensing is closer to what I was thinking of. I've heard of embedded sensor networks being used to: - help forecast earthquakes (hours before they occur, not weeks or months or years)...

After studying a little bit about the remote sensing i have a Question to ask that If i have a object inside the earth, on the Earth at rest and on the Earth which is moving how can i determine my Object on the earth?What sort of difference may i have to make in my satellite that to observe such...

I am having a projet in remote sensing apply geology, a homewok assigmen. It's a digging me. :cry: :redface: plZZZZZZZZZZ help me, contact me quick
