Radar is usually used only to determine where something is, not how large it is, because the strength of the reflection depends upon the reflectivity of the surface, the distance of the object, and the size of the object; a large wooden object can return less of a signal than a much smaller metal object, for example. It's too complicated a problem. But if you already know that you are looking, let us say, for an airplane, then radar is very good at showing you where the plane is.
What else can I help you with?
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 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.
How does radar calculate speed of an auto?
Radar calculates the speed of an object by measuring the Doppler shift in the frequency of the transmitted and received radar signals. As the radar waves bounce off the moving object, the frequency of the returning signal is different from the transmitted frequency. By analyzing this frequency shift, the radar system can determine the speed of the object.
Which rays does radar use?
Radar uses radio waves for detecting and tracking objects. These radio waves are emitted by the radar system and bounce off nearby objects, with the reflected waves then being detected by the radar receiver to determine the object's location and speed.
A method of finding the position of a solid object by sending out a pulse of high frequency radio waves?
This is likely describing the process of using radar technology to determine the position of a solid object. Radar works by emitting high-frequency radio waves towards an object and then measuring the time it takes for the waves to reflect back, allowing for calculations of the object's distance and position.
What is a bearing does in a radar?
It is the direction the radar is facing. It allows the radar to determine where the object is located in 2D or 3D space.

What is the difference between a Doppler radar and a regular radar?
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.
What does radar for?
Radar is a system that uses radiowaves to measure things like size, distance and speed of a specific object.
What kind of radio waves bounce off an object to determine its speed and location?

Does size determine an objects mass?
No, size does not determine an object's mass. Mass refers to the amount of matter in an object, while size typically refers to the dimensions of an object. They are related but independent characteristics.
What is raddar?
Radar is an object-detection system that uses radio waves to determine the range, altitude, direction, or speed of objects
What is the relationship of radar cross section with an object's ability to reflect or scatter radar signals?
The radar cross section of an object is a measure of how well it reflects or scatters radar signals. A larger radar cross section means the object is more likely to be detected by radar systems.
