Abstract:
    One laser radar which is used for the measuring the wind field as a pilot balloon is microwave modulating. including the system of the pulse laser and extending-string mirror; the receiving system including the telescope , optical fiber, narrow-cut filter; the frequently system is made up of the light-sensitive detector and the telescope; the data handling system is composed of the analog digital transmitting setting, the computer, the software modulation of amplitude of nanosecond pulse the laser radar, the Doppler shift of the scattering of the air molecule and the gas-solid is achieved by the microwave frequency. Compared with the measuring wind laser radar, the invention keep the good points of the directivity of the laser radar room, the high standard of the distinguishing ability .the intimation of the sending wave-length, is adapt to the different requirements of the aircraft and military. Pulse modulation improves the signal to mask radio greatly. The sending of laser radar and the frequency of technical methods own the advantage of both the laser radar and microwave radar, countering the balance of the disadvantage of the present technology, the invention means a lot to the development of laser radar and the popularization of it in our country.
