发布时间：2018-12-12 17:51
【摘要】：针对传统相控阵雷达易被干扰机侦察到方位信息从而实施干扰的问题,提出了一种基于FDA(频率分集阵列)的角度欺骗方法。通过在阵元间设定微小的线性频率差,将距离引入到FDA方向图函数,使得不同距离上的电磁波能量分布呈现弯曲特性,形成"虚拟辐射源",进而达到对侦察接收机的角度欺骗目的。此外,在分析欺骗原理的基础上,探究了频率差因子、阵元间距因子对欺骗的影响效果。Matlab仿真结果表明,在设定合适的因子后,对于特定距离处的目标该方法角度欺骗效果可达90°。
[Abstract]:Aiming at the problem that traditional phased array radar is easy to detect azimuth information by jamming machine, a method of angle deception based on FDA (Frequency Diversity Array) is proposed. By setting a small linear frequency difference between the array elements and introducing the distance into the FDA pattern function, the energy distribution of the electromagnetic wave at different distances presents a bending characteristic, forming a "virtual radiation source". And then achieve the purpose of angle deception to the reconnaissance receiver. In addition, on the basis of analyzing the deceptive principle, the effect of frequency difference factor and array cell spacing factor on deception is discussed. The Matlab simulation results show that, after setting the appropriate factor, The angle deception effect of this method can reach 90 掳for the target at a specific distance.
