| 摘 要： | 针对相控阵天线二可能值法随机馈相结果的不稳定性，提出了利用二可能值法和遗传算法相结合的解决方案．线阵天线为例对二可能值法进行了分析，指出了该方法的缺点所在，并对二可能值法和遗传算法相结合的方法进行了计算机仿真．仿真结果表明，2种方法相结合后的随机馈相效果优于二可能值法，此方法大大减低了二可能值法随机馈相结果的不稳定性．

| Abstract: | To settle the instability problem of the results obtained from randomizing phase feeding method with twoprobable values in phased array antenna, an approach is proposed by joint use of two-probable values method and genetic algorithms. Taking the linear array as an example, the disadvantage of two-probable values method is discussed. The computer simulation is made on the proposed method. The simulation results suggest that the randomi- zing phase feeding results from this proposed method outclass that obtained by simple use of two-probable values method, greatly reducing the instability in randomizing phase feeding results with only two-probable values method. |
