摘要
传统上航空测向交叉定位模糊区面积是几何近似分析,对这种近似分析带来的误差无法进行衡量。推导出了航空测向交叉定位模糊区面积的完整表达形式,并结合航空条件下测向交叉定位的特点,以此作为参照,通过仿真对此进行了对比分析。结果表明,2种方式误差较小,现有几何近似分析的结论可以较好地描述航空条件下的测向交叉定位模糊区的分布特性。
The traditional ambiguous area of aero-beam-crossing location is approximately geometric description, and the error of this kind of approximate analysis is inestimable so far. The complete formula of ambiguous area is deduced by means of geometry, and the two analyses are evaluated by simulation combining the characteristics of aero-passive location. The result shows that the error is so small that the approximate analysis can describe the distributed generalization of ambiguous area very well.
