Radar can be used to detect distance to an object by determining round trip echo time. Some uses below:
Level monitoring of substances in a container or silo-the radar antenna transmits downward from the top of the container and determines the distance to the top of the substance, allowing the operator to determine the amount of substance in the tank.
Radar can be used by vehicle collision avoidance systems.
Basically, any time distance to an object is required, radar is an excellent solution.

What is counterfire radar?
A counterfire radar identifies incoming artillery, rocket or mortar fire and determines the firing source so that retaliation can be immediate and effective. There are some counterfire systems that can use other sources besides radar, sound triangulation for example.
Who invented marine radar?
There is no "the" weather radar. Weather radars are a class of radars which can be used for gathering data on weather conditions. refer: http://en.wikipedia.org/wiki/Weather_radar The most commonly used weather radar at the moment is Pulse Doppler Radar. There was no 1 inventor of the PDR, so it was likely developed either by corporations or research labs. Refer to http://en.wikipedia.org/wiki/Doppler_radar#History for discussion on the origins of the more basic Doppler Radar.
What is radar navigation?
"RADAR" is an acronym for RAdio Detection And Ranging, which is a broadcast beam and receiver, used primarily to detect the objects (such as aircraft) which are at a distance that cannot be observed visually. It is one of the applications of microwaves. Radar is used along with advanced transponder technology in air traffic control. Smaller radar units have been used to measure the speed of cars and trucks on highways, using the Doppler effect (frequency shift for moving objects), although these have mostly been replaced with laser devices using the same principle. Radar is based on the principle that the RF signal at a high frequency is reflected back by reflective objects, typically large objects made from metal, composites, or rubberized materials. The distance between the radar antenna and the target can be measured by the delay time (microseconds, millionths of a second) between the broadcast and detected return. The reflected signal is known as a 'radio echo'. The time taken by the signal to travel one nautical mile is 6.18 micro seconds, so it requires 12.36 microseconds to reach and return from an object one nautical mile away. The formula to determine the distance of the object 'S' is S=T/12.34 where 'T' is the time taken for the transmission and reception of the signal. --- Radar is an acronym for RAdio Detection and Ranging. It uses RF transmission (radio frequency) in the microwave band to detect and range any detectable target within its range. It is an "active sensor" which emits RF waves that bounce off a target and are detected when the wave is received back. The time delay between transmission and detection produces its range given that the RF wave propagates at a uniform speed. Modern "stealth" aircraft use RF scattering, along with microwave-absorbing materials, to avoid detection by traditional radar. Some advanced planes have radar reflection signatures so low that they are less than those of small birds.
Can radar detect?
Doppler radar is used to measure speed, not temperature.
Defferential cw radar and pulsed radar?
CW Radar or Continues Wave Radar uses a constant transmission and is usually used for angle only tracking and can be combined with a second emission that is pulses or swept to deuce range using and separate antenna (or on a time schedule in some cases). The CW part of a CW Radar reference to the transition duty Ratio and because Dead and Listen time are over lapped they normally have two antennas. FM CW Radar or Frequency Modulated Continues Wave Radar, is similar to the CW set up but the Carrier Radio Frequency is swept, when processed this data can produce range data. Again the Dead and Listen time our overlapped and it is normal for separated antenna to be used. The Frequency sweep is repeated in successive management ion different angles Pulsed Radar Transmits a short pulse rather then continuously like the FMCW Radar or CW Radar and has a short Dead time and long listen time During the dead time when the transmission pulse is emitted the receiver is blanked to protect it, After the pulse has completed transmission the receiver is opened to receive the returns. This means that the receiver and transmission times are mutually exclusive and therefore the same antenna can used for both jobs. As the pulse is short the transmission peak power maybe higher then the CW Power but is present for less time. A Hybrid Radar is ICW or Interrupted Continues Wave (some times called Interrupted Carrier Wave) which is really a pulse radar with a high duty cycle.
What are some ways science and technology have helped predict the weather?
radar
What are the things that reporter of weather use to find out weather?
Doppler radar, thermometer, barometer list goes on and on there has to be some website about this.
What devices that are related to meteorology?
weather balloons, Doppler radar, and satellite imaging are some examples
Are weather maps and weather radar the same?
No. A weather map is an illustration that represents different components of the weather. Common elements of a weather map include wind speed and direction at various points, isobars (lines of equal barometric pressure), fronts, and high and low pressure systems. Some weather maps outline areas where there may be rain, snow, or potentially dangerous weather. Weather maps are used in showing how the weather is expected to behave over the course of a few hours or days. Weather radar is a technology that involves scanning the atmosphere with a beam of microwaves. The radar beam bounces off things such as rain and snow in the air. The signal that bounces back to the radar can be used to tell things such as where it is raining, how much, and sometimes how fast the wind in a storm is blowing. Doppler radar is used in tracking weather on a timescale of minutes.

What weather instrument sends out radio waves to see hundreds of kilometres?
You may be thinking of weather RADAR. It sends out radio waves, some of them bounce off of rain, snow, or the boundaries of layers in the atmosphere, and the radar receiver detects the waves that bounce off of something and come back.
What type of radar is used for detecting tornadoes?
Tornadoes are detected using Doppler weather radar. In recent years some of these radars have been upgraded with dual-polarization to further aid in detectng hail and tornadic debris.
What is the time periods for snow and rain on the oceans?
Well, it can't really be calculated unless you have a Doppler radar or some other kind of weather tracking device. Try looking for a website that has a weather tracker on it.
What are some other physical features besides blubber that help to keep animals warm in cold weather?
Rabbit fur
Where do airplanes fly to avoid the weather?
Airplanes with the aid of radar or simply by the pilot looking outside can navigate around the weather by going around it left, right, above it, below it. In some cases even returning to point of origin. Weather is something pilots monitor constantly.
From where does a weather forecaster obtain the information about weather?
The NOAA has several Satellites and other ground based equipment to monitor the weather. This information is given to people throughout the country for this purpose. Some television stations have their own radar for this purpose. Other countries use NOAA or have similar companies.
Will a radar detector interfere with my cell phone?
No but some phones will interfear with the radar detection.
