摘　　要：常规发射机调谐控制方法的调谐控制效果较差,无法降低发射机发射信号的失真度。针对此问题,本文以大功率中短波发射机为例,提出了一种全新的发射机自动调谐控制方法。首先,根据中短波发射机基本组成结构,使用采集设备采集发射机信号;其次,根据发射机运行特征与调谐需求,设定发射机PN码、帧格式与跳频等自动调谐控制参数;最后,以此为基础,分别从发射机前级与末级两个角度进行自动调谐控制,使发射机调谐控制状态达到最佳。由实验分析可知,新的方法应用后发射机信号失真度较低,发射信号质量较高,控制效果优势显著。Conventional transmitter tuning control methods have poor tuning control effect,and cannot reduce the distortion of transmitter transmitted signal.In order to solve this problem,this study takes the high-power medium and short wave transmitter as an example,and proposes a new method of transmitter automatic tuning control.First of all,according to the basic composition and structure of the medium and short wave transmitter,the transmitter signal is collected by the acquisition equipment.Secondly,according to the transmitter operation characteristics and tuning requirements,set the transmitter PN code,frame format,frequency hopping and other automatic tuning control parameters.Finally,based on this,the automatic tuning control is carried out from the two angles of the front stage and the last stage of the transmitter to achieve the best tuning control state of the transmitter.The experimental analysis shows that the transmitter signal distortion is low,the transmission signal quality is high,and the control effect is significant after the new method is applied.
