基于WGS-84地球等效参考椭球,构建了较为实际的两部2D雷达组网目标高度观测模型,提出了一种新的雷达情报组网目标高度估计方法,并通过大量仿真分析和对比了该算法的性能.理论分析与仿真证明,该算法模型考虑了雷达电磁波信号在大气中的传播折射问题,以及地球曲率对雷达观测的影响,充分利用了各雷达的量测信息,更贴近雷达观测的实际,能显著提高目标高度估计的精度,并且计算量小、运算速度快,具有一定的工程应用价值.%An effective measurement model of altitude estimation in 2D radar network with 2 sensors which is based on the WGS-84 ellipsoid earth is designed, and a new algorithm of aircraft altitude estimation with 2D radar intelligence networking is presented. Through a lot of simulations and academic analysis, the performance of the algorithm is analyzed thoroughly. The simulation and analysis result shows that the proposed algorithm considers the refraction of electromagnetic wave in the atmosphere, and the effect of the earth curvature to the observations. This algorithm accords to the fact of observation, and made full use of the measurement, so the estimation of Aircraft altitude was improved; together with the less quantity of calculations and the rapid operations, the proposed algorithm has fairly great practical value in engineering application.
