炮弹无线电引信信号分选识别是炮弹无线电引信干扰机的关键技术之一。由于炮弹留空时间短,同时无线电引信的工作频段又是无线电通信和电视、广播信号密集的频段,因此这一技术的主要困难点在于实时实现高分辨率信号处理。该研究采用了如下新技术和新方法:1 复数信号最大熵谱估计方法,有效地利用了信号的频带和最大熵方法的高分辨率特性。2 用高速数字信号处理器 TMS32010实现谱估计及信号识别算法,仔细进行了软、硬件设计,使得处理器的性能得以充分发挥。
Shell radio fuze signal sorting identification is one of the key technologies of the artillery radio fuze jamming machine. Due to the short space left in the shells and the working frequency band of the radio fuzes, which are also radios and television and radio frequency intensive bands, the main difficulty of this technique lies in real-time high-resolution signal processing. The research adopts the following new technologies and new methods: 1 The method of maximum entropy spectrum estimation of complex signals effectively utilizes the high-resolution characteristics of the signal band and maximum entropy method. 2 with high-speed digital signal processor TMS32010 spectral estimation and signal recognition algorithm, careful software and hardware design, making the processor’s performance can be fully exerted.
