| 摘 要： | 广域监视动目标检测(WAS-GMTI)模式作为机载监视雷达的一种重要工作模式，可以在较短时间内对大范围区域进行动目标监视，并进而对检测到的动目标进行快速定位，但在实际工程实现中，动目标的定位受到诸多因素的影响，直接使用理想公式对动目标进行定位存在较大误差。从战场或者交通监测的需求出发，广域监视动目标检测模式下需要对检测到的动目标进行快速定位。该文根据机载广域监视动目标检测模式下可以获得的动目标信息的特点，采用一种快速定位方法实现动目标的定位。同时对实际存在的导致动目标定位误差的这些因素进行了分析，并在考虑这些因素之后对动目标进行了重新定位。仿真和实测数据验证了该文对动目标定位误差的分析的合理性。

| Abstract: | As an important mode in airborne radar systems, Wide Area Surveillance Ground Moving Target Indication (WAS-GMTI) mode has the ability of monitoring a large area in a short time, and then the detected moving targets can be located quickly. However, in real environment, many factors introduce considerable errors into the location of moving targets. In this paper, a fast location method based on the characteristics of the moving targets in WAS-GMTI mode is utilized. And in order to improve the location performance, those factors that introduce location errors are analyzed and moving targets are relocated. Finally, the analysis of those factors is proved to be reasonable by simulation and real data experiments. |
