摘　　要：火箭尾焰造成的信号衰减是地面测量点位选择重点考虑的问题,通常采用传统β角确定火箭尾焰对遥测地面站接收信号的影响程度。针对新型固体火箭发射中β角分析法对遥测地面站接收信号情况预测不准确的问题,文中在分析影响遥测地面站信号接收因素的基础上,提出了一种采用信号衰减方向性预估遥测地面站接收信号情况的模型。通过分析火箭遥测实测飞行姿态、位置以及地面遥测设备实际跟踪信号情况确定了模型参数,并通过实例计算证明了该方法优的优越性。Flame decay is a key consideration of distributed telemetry stations in the selection of ground measurement points.The traditional method is to determine the influence of rocket flame on received signal from telemetry ground station by usingβangle.In the launch of new solid rocket,the angle analysis method is inaccurate to predict the received signal of telemetry ground station.To solve this problem,a prediction model of received signal condition was proposed.The model was realized by characterizing the directivity of signal attenuation.Parameters of the model were determined by analyzing the actual flight attitude,position and actual tracking signal of ground telemetry equipment.Additionally,a practical calculation was given in this study to verify the method superior to the traditional method.
