某型多卜勒雷达频率调制转换基准插件的FPGA实现

The FPGA Implementation of the Frequency Modulation- Transposition-Standard Unit for a Doppler radar type

某型多卜勒导航雷达广泛应用于军事和民用领域,调制转换基准插件是其核心部件之一。本文介绍一种采用数字控制振荡器的设计技术,利用FPGA实现调制转换基准插件功能,从而代替了原来的模拟部件,解决了设备的维护问题。

A Doppler radar type is widely used in military and civil aviation field. The frequency modulation- transposition-standard unit(MTSU)is one of its core units. The appearance of programmable logic devices(PLD), such as CPLD and FPGA, makes it possible to substitute the unit by a new module using FPGA with NCO technique. In this paper a FPGA implementation technology replacing the MTSU functions is introduced.
