摘要 由于可以在较短时间内对大范围区域进行动目标监视，广域监视动目标检测(Wide Area Surveillance, WAS-GMTI)模式已经成为机载监视雷达的一种重要工作模式。目前具备WAS-GMTI工作模式的系统较少，实际数据较难获得，严重影响了对WAS-GMTI中相关处理算法的验证。该文提出一种基于电子地图路网信息的WAS-GMTI动目标点迹仿真方法。该方法根据载机和电子地图路网信息直接产生动目标信息，避免了仿真场景回波所需的大量运算，而且产生的动目标信息可以合理地融合到真实地理环境中。此外，联合对同一动目标的多次观测信息，该文还给出了一种动目标的轨迹关联方法。仿真结果验证了该文所提方法的有效性。
Abstract：Wide Area Surveillance Ground Moving Target Indication (WAS-GMTI) mode is an important mode in airborne radar systems since it can monitor extensive area in a short time. However, there are few systems that possess WAS-GMTI mode. Therefore, real data of WAS-GMTI mode are difficult to obtain which have a great impact on the corresponding algorithm validation. In this paper, a target trajectory simulation method combined with electronic map is proposed. Since information of moving targets is based on information of platforms and electronic maps, simulating the echo of scenes can be avoided. Furthermore, the moving targets are combined with geographic environment reasonably and repetitious information of the same target can be used in tracking. Simulation results demonstrate the effectiveness of the proposed method.
