Naturally , all of these questions can be answered. The most effective and precise solution to these questions is radar. Radar can track down enemy's aircrafts and missiles, transfer signals from earth to orbit back and forth, measure the change in climate and help the police to catch and calculate the speed of any commuters. The applications of radar in peace time and war are absolutely endless.
Radar simplifies our living environment in peace time and determines victories in war.
The history of radar is quite long and amazingly unique. It traces back to the year of 1924 in the lab of Sir Edward Victor Appleton. Since the beginning of the 30's, radars have been developed rapidly to optimize their potentials. Many kinds or versions of radars have built to serve in our everyday life as well as the military. Each kind of radar is designed to do a certain job and therefore has different operational characteristics.
