Wind-finding radar

Abstract

The invention discloses wind-finding radar comprising a master control computer, a signal acquiring separator, a balance amplifying photoelectric detector, a radar speed calibrator, a pulse transmitter, an optical transceiving scanning system, an optical filter and an optical circulator. The radar speed calibrator comprises a fiber delay, a first microwave modulator and a first fiber coupler. The optical transceiving scanning system comprises a wind field scanning driver, an optical scanning prism and an optical transceiving antenna. The input end of the balance amplifying photoelectric detector is connected to the output end of the optical circulator. The wind-finding radar is simple in structure, low in cost, convenient to manufacture and maintain and handle and quick to move; for signal light and reference light, the fiber delay enables the signal light to pass 100m of an optical fiber and then enter a signal acquisition system, thus the signal light is delayed and the reference light and the signal light are effectively separated; the wind-finding radar is suitable for use in places with rain, ice and snow and flying birds and in any weather conditions.

Description

technical field [0001] The invention relates to the field of detecting high-altitude atmosphere, in particular to a wind measuring radar. Background technique [0002] At present, for the detection of high-altitude atmospheric inhomogeneities, the most widely used equipment in China is the wind profiler using electronic scanning technology. This wind profiler is a Doppler radar. The disadvantages of Doppler radar are: First, the structure is complex, the volume is large, and it is difficult to move. Second, because of its complex circuit and many components, not only the cost is high, but also the failure rate is relatively high, and the workload of daily maintenance is heavy and difficult to maintain. Third, due to the use of electronic scanning, the working frequency is high and the requirements for the use environment are high. It is especially sensitive to moisture, rain, snow, flying birds, etc. in the atmosphere, which often affects the accuracy of data collection and...
