Radar is an object-detection system which uses electromagnetic waves—specifically radio waves—to determine the range, altitude, direction, or speed of both moving and fixed objects such as aircraft, ships, spacecraft, guided missiles, motor vehicles, weather formations, and terrain. The radar dish, or antenna, transmits pulses of radio waves or microwaves which bounce off any object in their path. The object returns a tiny part of the wave's energy to a dish or antenna which is usually located at the same site as the transmitter.

The modern uses of radar are highly diverse, including air traffic control, radar astronomy, air-defense systems, antimissile systems; nautical radars to locate landmarks and other ships; aircraft anticollision systems; ocean-surveillance systems, outer-space surveillance and rendezvous systems; meteorological precipitation monitoring; altimetry and flight-control systems; guided-missile target-locating systems; and ground-penetrating radar for geological observations. High tech radar systems are associated with digital signal processing and are capable of extracting objects from very high noise levels.

A radar system has a transmitter that emits radio waves called radar signals in predetermined directions. When these come into contact with an object they are usually reflected and/or scattered in many directions. Radar signals are reflected especially well by materials of considerable electrical conductivity—especially by most metals, by seawater, by wet land, and by wetlands. Some of these make the use of radar altimeters possible. The radar signals that are reflected back towards the transmitter are the desirable ones that make radar work. If the object is moving either closer or farther away, there is a slight change in the frequency of the radio waves, due to the Doppler effect.

We're going to show you the hottest photos of one of the world's most gorgeous women, the girl who makes Donald Trump famous, Ivanka Trump.

Personally, I don't think we get to see nearly enough stunning photos of Ivanka Trump, which is surprising considering the fact that she's Donald Trump's scorching hot daughter and she appears pretty often on TV. Let's face it, there are only two reasons why you'd ever watch The Apprentice: a) you like to see other people getting fired and b) Ivanka's there as well. I know that's exactly why you're watching it.

So, I thought it would be a great idea to gawk at this drool inducing gallery that perfectly demonstrates why Ivanka Trump is one of the most amazing women in the world: she has a unique and stunning look, she has a killer body and she just oozes the ultimate hot appeal any time you see her, she's really classy and chic and she's also pretty damn smart.

She's like the perfect combination between beauty and brains, but unfortunately she's so far out of the average guy's league it is almost embarrassing for humankind. She's also married and she's going to have a baby soon which means we won't see her looking like this for long. Or maybe, who knows?
