Introduction介紹

很久以前有一個(gè)關(guān)于雷達(dá)發(fā)生的有趣故事。 一個(gè)駐扎在偏遠(yuǎn)村莊的雷達(dá)軍隊(duì)，一開始，小偷總是從軍隊(duì)偷走蔬菜。 所以指揮官告訴整個(gè)村民，他知道有人總是從軍隊(duì)偷蔬菜，因?yàn)槔走_(dá)可以檢測(cè)到一切，他希望這樣不會(huì)再發(fā)生。 漸漸地，這個(gè)村莊變得和諧，氣氛很好。 有一天，，聯(lián)誼會(huì)主任b director了指揮官。 她告訴警官，今晚有一對(duì)新人會(huì)進(jìn)入新娘的房間，但新娘因?yàn)闊o(wú)所不在的雷達(dá)而害羞。 雷達(dá)足以創(chuàng)造理解。 那么什么是雷達(dá)？ 雷達(dá)的功能是什么？ 也許我們很多人不能完全回答這個(gè)問(wèn)題。
There was an interesting story about radar happened in long time ago. A radar army stationed in a remote village, and at the very start, the thief always stole vegetables from the army. So the commanding officer told the entire villager he knew someone always stole vegetables from the army because the radar can detect everything, and he hoped that nothing like this would happen again. Gradually, the village became harmonious and had a good atmosphere. One day, the sorority director met the commanding officer bashfully. She told the officer that there was a new couple would go into the bride’s room tonight, but the bride was shy because the omnipotent radar. Radar is enough to create understandings. So, what is radar? What is the function of radar? Maybe many of us cannot answer the question completely. 

Detailed Information about Detecting Laser Radar關(guān)于檢測(cè)激光雷達(dá)的詳細(xì)信息

Radar is an electronic equipment that using electromagnetic wave to find the objective and determine its special location. The detecting laser radar is invented to detect 30 km to 100 km distancing from the ground even higher upper atmosphere.
The atmosphere section is difficult to detect, because this atmosphere section is extremely pure and there is no aerosol. Detecting laser radar is the most effective measure to detect this atmosphere section. 
What is the principle of detecting laser radar? It is formed by three parts: launching laser, using optical telescope to receipt, and using echo signal to detect. The differences are that the energy of laser is stronger than ordinary radar and the sensitivity is higher than ordinary radar1．
The detecting laser radar is invented by Chinese Academy of Sciences, the Mathematical Sciences Institute in Wuhan city plays an important role in the invention, and the invention of detecting laser radar is our own patented technology absolutely. A model was firstly presented by a member of the Mathematical Sciences Institute. And a solution was gotten, which can represent density distribution by the data obtained from the detecting laser radar. So we can obtain accurate and reliable measurement data from the detecting laser radar. The solution is obtained from multiple experiments and discussions. There are many factors should be considered, just as amplitudes, the width of the detecting laser radar and different pulses2．These factors are very important for the design and improvement of the laser radar.
The international technology of laser radar also is very advanced. The international studies of radar have shown great growth in the last 20 years. The growth is multiple and variortainty distribution of direct-detection laser radar with a peak-detecting routine’. Volume 124, Issue 21, November 2013, Pages 5202–5205.
