摘要
自适应天线阵列将阵列天线和自适应信号处理技术相结合,具有在空域有效抑制强干扰的能力。论文从阵型、阵列参数的分析出发,采用电磁计算软件FEKO对圆环阵列建模仿真,并利用遗传算法在考虑SIR(信号与干扰功率比)和不考虑SIR的情况下分别对各阵元的相位值进行优化以达到抗干扰的目的,结果表明,考虑SIR的优化使圆环阵列的抗干扰能力更强,更符合实际工程的需要。
Adaptive antenna array combines array antenna and adaptive signal processing technology together,and has the capacity of effectively restraining strong interference in airspace. The paper starts from the analysis on formation and array parameters,adopts the electromagnetic calculation software FEKO to make Circular array modeling and simulation,and optimizes the phase values of various array elements via genetic algorithm in the circumstances of taking SIR(signal to interference plus power ratio)and of not taking SIR into consideration separately to achieve the purpose of anti-interference,and the result shows that the optimization taking SIR into consideration results in more powerful anti-interference capacity of circular array,and conforms to the needs of practical engineering more.
