摘要
依据常见的激光制导信号具有周期性的特点,提出了一种基于频率的混合激光制导信号批次分选方法。在获取了混合信号的骨架周期后,在周期内逐次提取不同频率的单路信号,实现对混合信号的批次分选。仿真结果证明该方法能够对多种常见的混合激光制导信号实现快速准确的分选。
According to the periodical characteristic of laser guidance signal, a new classifying method based on the frequency is proposed. The frame period of the compound signal is firstly acquired. Then every single signal is picked out by the difference of the signal frequency within the frame period. The simulation results show that most periodically coded signals can be exactly extracted in a short time.
