On the basis of the detection principles of the new generation Lwave radar, the difficulties existing in the detection of strong wind weather with Lwave radar at lower altitudes and low elevation angles in island observation stations are discussed. Particularly， the phenomenon of balloon loss and sidelobe balloon at lower altitudes and low elevation angles are analyzed. A solution for balloon loss at lower altitudes and low elevation angles under strong surface winds, identifying the appropriate elevation range by means of downstream winds, is presented. Some experiences are also given, which can be used as reference for better use of Lwave radar
