%X Thermal noise and wind gust are the most significant random disturbances to radar angle tracking. The optimal servo crossover frequency is formulated by a functional of the RMS sum of thermal noise error and wind gust error. Then it is derived to be a function of AGC (Automatic Gain Control in receiver) voltage and average wind velocity sampled by a computer.Thus, a quasi-gain scheduling adaptive servo system is proposed. The effectiveness of the proposed system is illustrated by mathematical analysis and field experiment results.
