摘要
从几何稀释精度的角度,分析了有源雷达定位、红外探测器定位以及有源雷达与红外探测器组网定位这三种方法的定位精度。其中,组网的数据融合采用简化加权最小二乘估计算法。通过仿真比较了上述三种方法的定位精度随距离与高度的变化情况,得出有源雷达与红外探测器组网兼具有源雷达和红外探测的优势,优点是探测精度高、定位精度受高度影响较小,具有一定的现实意义。
There are three methods for locating precision of active radar,infrared detection and network of active radar and infrared detection according to GDOP. The data fusion of network adopts SWLS algorithm. To analyze the relationship between locating precision and distance together with height for these three methods,simulation indicates that network method has the advantages of both active radar and infrared detection,such as high locating precision,low height dependency and so on. So network method is a significative method.
