本文研究了应用幅度束控实现线阵波束扫描的问题,给出了傅里叶变换和逐步逼近法两种综合方法,并对逐步逼近程序进行了改进。通过数值计算讨论了幅度束控扫描阵的特点并和相位补偿阵进行了对比。
This paper studies the problem of using linear beamforming to realize linear beam scanning. Two methods of Fourier transform and stepwise approximation are given, and the step-by-step approach is improved. The characteristics of the amplitude-controlled scanning array are discussed by numerical calculation and compared with the phase-compensation array.
