radar is acronym for radio detection and ranging--ergo a high freq. pulse is sent out and returned be it reflection from weather planes autos.etc. the time it takes to transmit and receive this pulse gives range. In most cases directly received power from the transmitter to the target and back to the receiver are termed echoes (or target echoes) and indirect received power from the transmitter power bouncing off some intermediate surface between the transmitter and the target and/or the target and the receiver are what people call reflections, this is also called "multi-path effects". You should also look at glint and scintillation. All object the "reflect power" or provide a echo are termed scatters.
Radar!
As far as I know, radar was invented by a Hungarian scientist named Zoltan Bay. That radar was first used in World War II by the British troops.
No world is a stage, and you cannot detect a helicopter unless you have the radar station (radar alone is not sufficient)
Normal radar sends out radio waves to determine the location of an object. Doppler radar can not only find the location of an object or storm, but using something known as the Doppler effect can determine how fast it is moving towards or away from the radar.

which reflects the radiating signals
Microwave radiation is commonly used for radar systems. This type of electromagnetic radiation has the properties necessary for radar applications, such as the ability to easily penetrate through various weather conditions and return accurate reflections from objects.
yes, I developed a radar absorbing coating , which can simply be applied on nearly every surface. It is very tough (passable) and reduces radar reflections between 5 and >110 GHz by 99 ... 99,99 %. [mailto:arrow33@gmx.de arrow33@gmx.de]
Microwave radiation is the form of radiant energy used in radar systems. Radar systems emit pulses of microwave radiation and then detect the reflections of these pulses off of objects in order to determine their location, speed, and other properties.
Radar cannot determine the composition or material of an object, but it can detect and track the presence of objects based on their size, shape, and movement. Radar uses radio waves to detect the presence of objects by sending out pulses of electromagnetic energy and detecting the reflections off the objects.
A special type of radar called sonar is used to detect objects underwater by emitting sound waves and detecting their reflections. Sonar is commonly used in applications such as navigation, communication with submarines, and mapping the ocean floor.
On navigation charts, you may find a feature marked on the chart as 'Radar conspicuous'. This means that the feature will show up clearly on radar and be identified as that part on the chart.This not so obvious as it sounds. Land shows up on ship's radars, but due to reflections, absorption of radar signals and refraction, it can not always be certain to positively identify a coastline by it's shape.Having something that stands out, because of it's shape and radar reflection, is useful for navigation purposes.
the primary radar mostly we used for air traffic control and other civil society work but this primary radar will not cover the whole requirement data. But secondary radar system will give all the details which we required Also mostly we used for it for security purpose and we can take the IFF and SSR from this secondary
To create a small radar to track mobiles, you would need radar modules, microcontrollers (such as Arduino or Raspberry Pi), power source, display screen, and software for signal processing and displaying the mobile locations. The radar would emit electromagnetic waves, receive the reflections from mobile phones, and use signal processing algorithms to calculate their location. Keep in mind that building such a device may involve legal and privacy considerations.
Ground penetrating radar (GPR) is commonly used to detect water leaks underground. GPR works by sending radar pulses into the ground and measuring the reflections to identify anomalies like water leaks. This non-invasive method is effective in locating leaks without the need for excavation.
