| 摘 要： | 给出2D多雷达组网中基于最大似然估计目标高度的方法,以及有先验信息约束条件下的目标高度估计误差的下界(CRLB)。对两种典型的空地雷达配置情况进行了仿真。讨论了不同空地雷达组网配置的情况、雷达和目标的相对位置、雷达距离和角度测量精度对高度估计精度的影响。文中的结论对空地一体化组网雷达的配置和管理具有一定参考价值。

| Abstract: | A method based on maximum likelihood to estimate the target height in 2-D radar network is presented. The CRLB of height estimation is also derived. Simulations are made for some typical configurations consisting of both ground-based and airborne radar. Some conclusions are drawn based on the numerical results for various conditions. The conclusions in this paper are useful in integrated air-ground radar-netting and in sensor management. |
