摘　　要：相控阵波束指向只具有角度相关性,而频率分集阵列(frequency diversearray,FDA)的波束指向具有更高的自由度.利用频率分集阵列波束图是时间、角度及距离的函数这一特性,研究了基于非线性FDA的多假目标欺骗干扰方法.首先建立基于FDA的干扰模型,之后给出基于FDA体制的雷达多假目标干扰公式,最后进行了仿真验证.仿真结果表明,采用平方频控函数的cubic-FDA多假目标欺骗干扰方法性能最优;随着频偏增量、信号带宽、信号脉宽取值的增大,多假目标干扰更为密集.Phased array beam pointing has only angular correlation,while frequency diverse array(FDA)beam pointing has higher degree of freedom.This paper uses the characteristic that the beam pattern of FDA is a function of time,angle and range to study the spoofing jamming method of multi-false targets based on nonlinear FDA.Firstly,a jamming model based on FDA is established,and then the formula of radar multi-false-target jam-ming based on FDA system is given.Finally,the simulation verification is carried out.The simulation results show that the cubic-FDA multi-false-target spoofing jamming method with square frequency control function has the best performance,and that with the increase of frequency offset increment,signal bandwidth and signal pulse width,multi-false-target jamming becomes more intensive.
