摘　　要：研究了多径和海面大气折射这两种环境因素对雷达搜索应答器最远距离的影响,使用PE方程计算了不同蒸发波导高度条件下导航雷达和应答器发射信号的传播衰减,通过对计算结果分析和解释,结合东海试验的实测数据,得出应答器天线高度的最佳选择。The influences of the two environmental factors,the multiple paths and the refraction of sea surface atmosphere,on the maximum detection range of the radar for the responder are discussed.The PE Equation is used to compute the signal transmission attenuation between the navigation radar and the responder with different evaporation duct heights.According to the analysis of the results and the test data taken at the East Ocean,the best selection of the height of responder antenna is achieved.
