| 摘 要： | 针对机载脉冲多普勒雷达主波束照射内、强杂波背景下的低空运动目标，讨论了一发两收双天线模型配置下，基于二单元DPCA技术对消地杂波、检测运动目标径向速度的方法，并给出了具体的计算公式。最后对具有不同速度的动目标进行了仿真，其模拟结果和理论分析相吻合，表明了无论目标出现在主瓣还是旁瓣，该方法都能有效地抑制地杂波和检测动目标的径向速度。 |

| Abstract: | For airborne two-antenna(one transmitting and two receiving)PD radar model,the low altitude moving targets received by main beam were mixed with strong clutter.Aiming at clutter suppression and moving target detection,a method was suggested to estimate radial velocity based on two segment DPCA.The formula was derived in detail.Finally,for moving targets with different velocities,simulation was carried out.The agreement of the final simulation results with the theoretical analysis indicates that this method could be used effectively to suppress clutter and estimate radial velocity of moving target whether it appered in mainlobe spectrum or in sidelobe spectrum. |
| Keywords: | airborne PD radar ground clutter DPCA moving target |
