某型塔康机载设备特性研究

Research on Characteristics of Airborne*TACAN

为了提高飞机空/空测距性能及满足微波着陆的需要,某型塔康在3型塔康的基础上研制出来;阐述了该机载设备的一些特点,如频率控制、询问飞机的数目及处理、接口控制关系、精确测距等,主要对429总线接口关系及控制单元进行了比较详细分析;结果表明,某型塔康具有小型化、自动化、数字化、模块化的特点,并且系统精度不断提高,容量增大了一倍,询问飞机数目也由原来的4架增加到5架,具有多种信号输出接口供用户选择,提高了空/空测距性能,为完成DME/P功能,采用了多种脉冲技术,因此满足精确微波着陆的要求;这些问题的研究对航空测位、测距系统产品开发将有一定参考价值。

For the sake of increase airplane function of air--to--air distance measurement and precision MLS （Microwave Landing Sys- tem）, ＊ TACAN is developed based on 3 TACAN. It is discussed some special problems such as frequency control, the number of airplane question and management, port control and precision distance measurement 、 It is main discussed 429 port control and control unit. It is tes tifled, ＊ TACAN is small, automatic, digital and modularized. The capacity and capability of the system have been increased, and the num ber of airplane question and management has changed from 4 to 5. The users now have more choices of the output ports. It adopts manifold plus techniques to complete DME/P, and it meets the need of the alr--to--air distance measurement and precision MLS （Microwave Landing System）. The study will be beneficial to the development of airborne equipment.
