【Abstract】 The background to the evolution of the high frequency sodar is reviewed. The principle of phased array is presented and so is the advantage of high frequency .sodar. Such kind of sodar is used for some special purposes. Being a remote sensing instrument, it is obviously with a promising future in an experimental mesoscale observing, network considering its lower cost as well as its satisfactory operations.更多还原
