  • 摘要:

    尽管全球导航卫星系统(GNSS)外辐射源雷达具有信号源广泛、覆盖率高、容易进行时间同步等特点,受到了国内外研究机构的广泛关注,但由于卫星位置变化和单颗卫星的目标探测性能有限,难以满足实际探测需求。根据几何构型给出GNSS外辐射源雷达双基地角计算方式,仿真研究双基地角与目标雷达散射截面积(RCS)的关系,分析探测时间与目标最大探测距离的关系,得到目标探测概率的理论表达式,并据此评估基于GPS L5信号的外辐射源雷达在单星、多源融合及前后向协同探测模式的目标探测概率。仿真结果表明:单星前向和后向探测模式的有效探测时间覆盖率不足1 %,采用前后向协同及多源融合的探测方式,可有效提升GNSS外辐射源雷达的目标探测性能至25 %;通过采用连续扫描检测的方式实时改变接收天线的照射方向进行目标探测,在前后向协同的多源融合探测模式下,有效探测时间覆盖率达到98.96 %,基本满足全天时有效探测需求。
