摘要 针对叶簇穿透超宽带合成孔径雷达面临其他多种电子系统的频谱干扰问题,提出一种在干扰频带设计陷波的相位调制雷达波形设计及频域处理方法。在建立最大化使用频带和干扰频带能量之比的模型基础上,通过相位域求解共轭梯度以较快的收敛速度得到近似最优相位调制波形。基于发射信号频谱研究了频域匹配处理和距离旁瓣频域抑制加权技术。通过该波形设计及处理方法,可以灵活并有效地完成抗窄带干扰,且易于工程实现。 To solve the problem of narrow band interference（NBI） from other electronic systems for foliage penetration ultra wide band synthetic aperture radar（FOPEN UWB SAR）,a new kind of phase-modulated waveform design method which minimizes the power spectrum in the interference bands and the correspondence frequency domain processing method are proposed.Penalization function is first constructed.The conjugate gradient algorithm in phase domain is proposed to realize optimized calculation.Last the frequency domain matched filter and unmatched filter for suppressing range sidelobe are studied.Simulation results show that this method can effectively suppress narrow band interference（NBI） and be realized in engineering.
