The effects that technology warfare did to the Americans and Japanese, due to the bombing of Pearl Harbor and the bombing of Hiroshima and Nagasaki were equal. Radar, the atomic bomb, high powered weapons and aircraft play an important role in these two events that will be talked about. The technology had to be right for these events or the events and plans possibly could have not happened. The invention of radar had a huge impact on many military operations, whether or not it was the United States Military or other countries. Radar was used to detect distant objects by receiving radio waves that are reflected from the object. (Foley 4)This helped air control personnel at the naval base of Pearl Harbor know that something was on its way to it. If the reader does not think about radar, where would the people be to this day? Attacks would be even more of a surprise. It would be harder for America to find their own military personnel and identify friendly or enemy vehicles. Radar has come a long way throughout the years. Radar stands for Radio Detection and ranging, it dates back to the 1880’s when Heinrich Hertz first invented it. (Farina 1-1) Many other inventors eventually started inventing their own type of radar. Christian Hulsmeyer in 1904 had a patent for monostatic pulse radar which was used for the detection of ships for preventing collision at sea. In 1922 A. Hot et al. observed a fluctuating signal at the receiver when a shipped passed between the receiver and transmitter. (Farina 1-1) There are many different types of radar used in the attack on Pearl Harbor and to this day. There were military radars, civil aviation radars, weather radars, mapping radar, impulse radar, radar guns, etc. During World War II, the devel... ... middle of paper ... ...ed States is a strong nation. Technology is still a very important thing to this day. If we did not have technology, where would the people be today? Works Cited .N.p.. Web. 4 Mar 2014. . Foley, Sean.
