How is radar similar to active sonar?
Radar and active sonar both emit energy pulses and measure the time it takes for the signals to bounce back after hitting an object. They both use the principle of echolocation to detect and locate objects in their respective mediums of air and water.
How a radar helps us?
AnswerRadar Help to detect object at the space and also transmit the pulses of radio waves which bounce off any object in their path.
What is locating objects by radio pulses?

What radar do?
At the minimum, a radar is a device that can detect the range of the target object (ie. radar gun used by law enforcement). A more advanced radar can locate the range and direction of the target object (via the azimuth). For example, the old spinning radar antenna seen on TV can locate an object based on the detected range and the direction the antenna is facing at the time. These can still be used to track the weather as clouds can be tracked. The most highly advanced radar can identify just about everything about the target object as if it is in front of you. An example of use is tracking space junk.
What is ground penetrating radar used for?
Ground penetrating radar (GPR) is a geophysical method that uses radar pulses to image the subsurface. When the waves hit an object, the receiving antenna can be used to distinguish what it is. This can be used to find precious metals, like gold, underground.
What is a radar PRF?
Radar Pulse Repetition Frequency - The number of pulses the radar system sends out to the target. A pulse can contain multiple frequencies.
Radar cannot determine?
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.
What form of radiant energy is used in radar?
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.
How can you determine distance using remote sensing?
A radar emits electromagnetic radiation via a transmitter, and it has a directional antenna that measures the time of arrival of backscattered or reflected pulses of radiation from remote objects. The distance between the radar and object can be deduced using the speed of light.
What is the palindrome for an instrument used to locate airplanes?

What is the palindrome for an instrument used to locate air planes?

What happens when radar beam hits an object?
When a radar beam hits an object, it gets reflected back towards the radar receiver. The time difference between sending the radar signal and receiving the reflected signal is used to calculate the distance of the object from the radar. The radar can also determine the object's speed and shape based on how the radar signal is reflected.
