Research on characteristics of the L-band EDFA gain clamping and enhancement;

Optimal design of L wave band plane microstrip array antennas;

In the course of setting up the L wave band wind measuring radar,there are large and fussy statistic work in each sounding station,so I compiled an automatic statistic program in my spare time which can statistic calculations automatically and save on the manpower and time.

To improve the sounding data utilization ratio in forecasting,the data type and gains way by using the L wave band meteorological sounding system as well as the prospect of the application in the weather forecasting is discussed.
