利用AGC电压预测及先验跟踪信息的遥测设备副瓣判决

Sidelobe Judging for Telemetry Equipment by Using AGC Voltage Prediction and Priori Tracking Information

针对无引导天线遥测设备副瓣判决难的问题,提出了一种结合自动增益控制(AGC)电压预测、跟踪稳定性判决及跟踪角度判定的副瓣自动判决方法。采用拟合方法建立了AGC电压预测公式并通过实测数据验证了其准确性。在分析遥测设备副瓣跟踪特点基础上,提出了遥测设备跟踪稳定性及角度差判定准则,最后设计判决软件实现自动副瓣判决。实验验证结果表明在判定准确度相同的条件下,采用该方法的耗时比人工判定缩短了48%。

It is difficult to identify the sidelobe tracking on telemetry equipment without guide antenna. To solve this problem, a new automatic sidelobe tracking judgment method is presented in this paper which combines the prediction of automatic gain control( AGC) voltage,the judgment of tracking stability and tac-king angle difference. A formula for predicting the AGC voltage is derived. Through the measured data vali-dation,prediction formula has better precision. Besides,by analyzing the features of sidelobe tracking,the tracking stability and angle difference criterion on telemetry equipment is put forward. Finally,the automatic process of sidelobe judgment is designed. The validated results indicate that the method proposed in this pa-per saves 48 percent of the time compared with the manual judgment.
