摘　　要：针对新型飞机超低空飞行和远程作战的通信需求,本文根据天线自动调谐的基本原理,采用以微处理器为核心的数字处理与控制技术,研究了由天线调谐参数检测器、匹配网络和控制电路组成的天线自动调谐系统,并对检测器的电路进行设计。天线自动调谐系统作为某型短波自适应/跳频电台的一个部件,已在多型飞机上得到应用。应用结果表明,电台在定频状态工作时,天调控制电路可存储XXX个收/发频率的调谐参数;电台在跳频状态工作时,天调控制电路可存储XX个频率参数;电台在自适应状态工作时,天调控制电路可存储XXX个频率参数。天线自动调谐系统不仅增强了天线自动调谐的智能化水平,改善了调谐性能,而且简化了调谐检测的信号处理和系统控制。该研究满足了现代飞机航程远、作战半径大以及超低空飞行的通信需求。According to communication needs for new aircraft flying at low-altitude and long-range, the study designed an automatic tuning system based on the basic principles of automatic antenna tuning, using digital-processing and control technology based an microprocessor. The system is composed of the antenna tuning parameter detector, matching network and the control circuit. Antenna automatic tuning system as a component of a type of short-adaptive/frequency hopping transceiver has been applied in multiple air- craft. Application results show that the tuning control circuit can store XXX tuning parameters of trans- mit/receive frequency when the transceiver works in the state of fixed frequency, and XX frequency param- eters when the transceiver works in the state of frequency hopping, and XXX frequency parameters when the transceiver works in the adaptive state. Automatic antenna tuning system not only enhances the intelli- gence level of automatic antenna tuning, and improves performance but also simplifies the signal processing and system control tuning detection. This study meets the communication needs of modern aircraft for long range, large combat radius and low altitude flight.
