Transcript: RADAR APPROACH RADAR Assess and Refine the deployed approaches based on monitoring and analysis of the results, i.e. measure whether it is working, identify what we have learned and what improvements can be made. ASSESS & REFINE Plan and develop the Approaches to deliver the required results, i.e. how are we going to achieve results? RADAR How will you use it? RESULTS Determine the Results the Company is aiming to achieve as part of its strategy, i.e. what are we trying to achieve and what does success look like? DEPLOYMENT Deploy the approaches in a systematic way to ensure effective implementation What's it all about? RADAR - a simple but powerful tool that can be applied to large projects or everyday tasks in order to help drive continuous improvement

Transcript: Types find and identify objects in water, determine water depth http://www.timetoast.com/timelines/history-of-sonar Daniel Colloden used an underwater bell to calculate the speed of sound at Lake Geneva, Switzerland. This led to other inventors experimenting with sonar. Lewis Nixon created the first sonar listening device to detect icebergs. Robert Boyle is recruited to create a sonar device, and beats all other countries in doing so. What it is A system for the detection of objects under water and for measuring the water's depth by emitting sound pulses and detecting or measuring their return after being reflected. Active sonar transducers* emit an acoustic signal or pulse of sound into the water. If an object is in the path of the sound pulse, the sound bounces off the object and returns an “echo” to the sonar transducer. Passive sonar systems are used primarily to detect noise from marine objects (such as submarines or ships) and marine animals like whales. SONAR SOund NAvigation and Ranging Facts Prior to the advent of sonar, mariners used lead lines to take systematic 'soundings' of the seafloor, which enabled them to produce early depth charts and bathymetric maps. Sonar was first used during World War I to detect submarines. By the 1920s, the U.S. Coast and Geodetic Survey—the precursor to NOAA’s National Ocean Service—was using it to map deep-water areas.

Transcript: ''Meteorologists use many different tools for different purposes. Most people are familiar with thermometers, barometers, and anemometers for measuring temperature, air pressure, and wind speed, respectively. Meteorologists use other tools, as well. For example, weather balloons are special balloons that have a weather pack on them that measures temperature, air pressure, wind speed, and wind direction in all the layers of the troposphere. '' http://www.gpb.org/blogs/talking-up-a-storm/2012/02/15/students-ask-how-do-meteorologists-predict-the-weather Cources ''The radio waves used by radar are produced by a piece of equipment called a magnetron. Radio waves are similar to light waves: they travel at the same speed—but their waves have much longer wavelengths and higher frequencies. The antenna doubles up as a radar receiver as well as a transmitter. Typically it transmits radio waves for a few thousandths of a second.''

Air traffic control uses radar to track planes both on the ground and in the air, and also to guide planes in for smooth landings. Police use radar to detect the speed of passing motorists. NASA uses radar to map the Earth and other planets, to track satellites and space debris and to help with things like docking and maneuvering. The military uses it to detect the enemy and to guide weapons. How does radar work What is Radar? RADAR How meteorologists use radar to predict weather
