| 摘要: |
| 泛探雷达利用同时多个接收波束覆盖整个观测空域，可利用长时间相参积累提高动目标检测性能，然而必须解决目标在长积累时间之内出现跨波束、跨距离单元和跨多普勒单元现象带来的积累增益下降问题。在跨波束影响可忽略前提下，研究了基于Keystone变换与Dechirping变换相结合的运动补偿方法，并在此基础上提出了基于Clean思想的多目标检测流程。通过对仿真数据与外场实测数据的处理与分析，验证了本文方法的有效性，可以用于泛探雷达的目标检测。 |

| Abstract: |
| Ubiquitous radar receiver generates multi-beam at the same time to monitor the area designated. It can use long-time coherent integration method to improve target detection performance. However, the crossing-beam, crossing range-cell and crossing Doppler-cell problem in long time must be solved to avoid the integration loss. A moving compensation method based on Keystone transform and Dechirping was researched in the case the crossing-beam impact can be neglected. A detecting flow for multiple targets using the Clean method was proposed. The method proposed in this paper was verified by the simulating data and the outfield experimental data processing. Results show that it can be used for target detection of ubiquitous radar. |
