RTX环境下副载频信号的实现方法

The Implementation of Subcarrier Frequency Signal in the RTX Environment

随着半实物仿真技术(HILS)的发展,对实验室条件下目标环境特性的模拟提出了越来越高的要求,特别是复杂调制信号的产生和验证已经成为被广泛研究的内容.针对硬件电路产生的副载频信号难以实现指令信息实时动态刷新的问题,提出一种利用RTX实时开发平台研究模拟产生副载频调制后的复杂射频信号的实现方法,并通过半实物仿真试验,验证了该方法的正确性和可行性.

With the development of the HILS （ Hardware-in-the-Loop Simulation）, the simulation of the target environment is expected to be more functional. Especially, the generation and verification of the complex modulated signal has been extensively studied. To resolve the problem that the subcarrier frequency-modulation produced by the hardware circuit can＇t refresh the instruction signal in real time, the implementation of complex RF signal was researched after subcarrier frequency-modulation with the help of the RTX platform and verified the correctness and feasibility of the method by carrying out the HILS test.
