摘要
现代战场电子环境日趋复杂,主瓣欺骗式干扰对雷达的生存能力构成严重威胁。传统阵列雷达无法对抗与目标角度相同的干扰,而以频率分集阵为代表的波形分集阵列雷达,通过发射端调制而具有额外距离维自由度,增加了系统设计与信号处理灵活性,为解决主瓣欺骗式干扰抑制难题提供了有效途径。本文总结了波形分集阵列雷达波束形成抗干扰的方法,指出其在对抗主瓣欺骗式干扰上的优势,并对波形分集阵列雷达抗干扰技术的难点与趋势进行了梳理。
The electronic environment of modern battlefield is becoming more and more complex,and the main-lobe deceptive jammer poses a serious threat to the survival ability of radar.For the traditional array radar can not resist the jammer with the same angle as the target.The waveform diverse array radar,represented by frequency diverse array,has extra degrees-of-freedom(DOFs)in the range domain by modulating the transmitter,which increases the flexibility of system design and signal processing,and provides an effective way to solve the problem of the suppression of mainlobe deceptive jammer.This paper summarizes the anti-jamming methods of waveform diversity array radar beamforming,points out its advantages in anti mainlobe deceptive jammer,and combs the technical difficulties and trends of anti-jamming in waveform diverse array radar.
