Yes. They have radars mounted in the nose that is used for viewing the weather conditions. Many of the newer "electronic cockpit" jets have CRT displays for their instrumentation and navigation. These can display weather conditions on the navigation screen. They can see their course that they have plotted out and see the severity of the weather displayed in multi-color format. I've seen a pilot turn on this weather radar while sitting on the ground a "look" up into the clouds before he ever takes off. Pretty cool.
Stealth aircraft are made so they don't show up on radar very well, or at all. This is important if you're going out to blow something up and don't want to be seen. Commercial aircraft could not be stealth aircraft because you really need to be able to see one on radar. Air Traffic Control uses radar to detect aircraft in its area, other planes use radar to detect you in the sky...having a commercial plane that couldn't be seen on radar would be very bad. - - - - - the difference is like police and thief.
A radarman in the US Navy is responsible for operating and maintaining radar equipment used for detecting and tracking ships, aircraft, and other objects. They interpret and analyze radar data to provide situational awareness to the ship or aircraft they are assigned to. They may also be involved in troubleshooting and repairing radar systems.
Generally no, but if used around any naval base or military aircraft facility you run the risk if their radar systems causing major damage to your equipment due to the strength of their systems.
Beneath the pilots feet are the control systems. In the nose is the radar
Aircraft will fly and transport people or cargo. Specialised aircraft can carry weapons and long range radar systems. Some aircraft like helicopters will hover and can land without runways.

semi stealth means that the aircraft is hard to detect on enemy radar systems giving the aircraft the upper hand in a dogfight. the F-22 is a prime example of this.
The modern uses of radar are highly diverse, including air traffic control, radar astronomy, air-defense systems, antimissile systems; marine 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.

An altimeter (altitude meter) tells the pilots how high the aircraft is flying. There are 2 types of altimeters commonly used in aircraft: pressure altimeters and radar altimeters.
Avionics is a portmanteau of the words aviation and electronics.
An American aerospace firm, Lockhead Corporation, an American research and development firm Northrop Corporation, invented it. The first generation of radar-invisible aircraft, stealth planes were designed to elude enemy radar systems.
