RADAR is basically a device which can measure the distance between two objects and also used for weather forecasts. The principle involved in RADAR is that it incident laser From Barry: microwave radiation, actually on a particular object and the object strikes it back to the point from where it was incident. Thus it gives the information about the distance and direction between the two objects.

RADAR has now become obsolete due to various new techniques with much higher speed and accuracy are available now, but even today many military operations and weather forecasts are still based on it.

RADAR provides outstanding graphics in case of weather forecasts. It changes the colors of areas according to the temperature of that area.

RADAR can be improved by using high frequency Radio Waves and proper path and energy is given to the waves.

Barry's Response - A few interesting thoughts on the subject.

This works for police traffic radar as well, but it has an added dimension. Doppler.

Doppler radar measures a phase shift in the returned signal and the support software uses that difference to calculate the speed of the object, but only the component of the speed towards or away from the RADAR. A single image cannot be used to tell if it is moving sideways or how fast.
