Adaptation of Radar Tracking Systems to Random Disturbances
雷达跟踪系统的随机干扰自适应

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.
