摘要
针对有限大平台部署多种传感器导致的严重的自干扰问题,提出了一种应用遗传算法实现的阵列天线共址干扰抑制技术。首先针对同平台上的阵列天线和其他天线建立了辐射和接收模型,然后将辐射特性和接收机抗干扰特性分别抽象为最优化问题的目标函数和约束条件,最后通过遗传算法进行最优化求解。该技术在不同辐射角度时能抑制共址干扰,具有一定的工程实用价值。
A co-site interference suppression technique for antenna array using genetic algorithm(GA) is proposed to solve the self-interference problem caused by the deployment of multiple radio frequency(RF) sensors on a finite platform.Firstly, transmitter and receiver models are built for transmitting antenna array and receiving antennas respectively.Secondly, the radiation characteristics and anti-interference properties of receiver are abstracted to the objective function and constrains of an optimization problem and finally GA is involved to solve it.The technique can suppress the co-site interference with varying azimuth angle of the antenna array and has practical engineering value.
