摘  要:针对高频雷达面临的干扰严重、目标雷达散射截面(Radar Cross-Section,RCS)起伏等问题,提出将靶场雷达中的多频探测技术引入高频雷达,大幅降低了干扰和RCS起伏对雷达系统目标检测能力的制约,同时提出了一种基于非相干积累的多频信息融合技术,将多频点数据在速度域上进行非相干积累,获得高信噪比,进一步提升高频雷达目标检测能力.通过仿真和实测数据验证,上述方法能够在原有信噪比基础上得到提升,与理论值相近.证明该方法有效.Based on serious interference and target fluctuation which HF radar is faced with,it is proposed that multi-frequency detection technique from range radar is applied to HF radar to overcome the restrict the above problem mentioned.Moreover,this paper puts forward an algorithm of multi-frequency information fusion based on non-coherent integration.The algorithm makes non-coherent integration in speed domain,obtaining high signal-to-noise ratio to improve the ability of target detection in HF Radar.Through both simulated and experimental data,the proposed algorithm can improve the signal-to-noise ratio close to the theoretical value,which indicates that this algorithm is effective.
