摘　　要：宽带雷达目标回波信号由于距离扩展和低信噪比,导致传统宽带检测器对目标分布特性先验要求较高,在目标散射分布特性未知的情况下存在检测跟踪性能快速退化问题。针对此问题提出了一种利用多检测特征融合的宽带检测方法,在无需目标散射分布先验特征的情况下,将多参数径向积累与顺序统计量检测融合判决,有效提高宽带雷达目标检测的稳健性。根据多特征融合检测结果,采用宽带包络相关测距和单脉冲测角技术实现高精度的目标跟踪处理。仿真实验验证了该方法的有效性。Wideband radar echo has the problems of range extension and low signal-tonoise ratio,which makes traditional detectors have higher requirements on the priori of the target scattering characteristics.When the target scattering distribution characteristics are unknown,there is a problem of degraded detection and tracking performance.In order to solve the problem,a wideband detection method through multi-detector feature fusion is proposed.Without the priori of the target scattering distribution,the radial accumulation detector with different parameters and the sequential statistics detector with different parameters are fused and judged to improve the robustness of wideband radar target detection.Using the results of fusion detection,by adopting broadband envelope correlation ranging,single pulse angle measurement to achieve robust target tracking under wideband conditions.Finally,the effectiveness of the method through simulation experiments is verified.
