Abstract

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。
