<p><P>PROBLEM TO BE SOLVED: To provide a small-sized, light weight and inexpensive new type wind speed radar of simple structure having a functional level same to phased array system one high in performance as a radar for measuring the wind speed and a wind direction of an air current in the atmospheric layer. <P>SOLUTION: This wind speed radar A<SB>1</SB>is provided with a spherical radio wave lens 1 of a Luneberg lens, and a plurality of sets (5 sets) of primary radiators 3 respectively in a zenith to be measured contacting with an outer circumference thereof, and in a focal position of a radio wave corresponding to an azimuth direction forming a zenith angleθwith respect to the east, west, south and north, and is constituted to reflection-return by the air current the emitted radio waves emitted switching the radio waves from an oscillator inside a control box 10 toward respective directions, and to receive the weak radio wave by a receiver to obtain a measured data of the wind direction. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
