摘要
数字信道化接收机是一种比较优秀的电子战接收机。采用瞬时测频技术可以有效地消除相邻信道的虚假输出;利用非相干积累技术可以克服固定门限检测的缺点;跨信道信号的检测及恢复技术可以解决宽带信号的跨信道问题。仿真实验证明了以上方法的有效性,这些技术的采用可使数字信道化接收机早日实现实用化。
Channelized digital receiver is a more excellence EW receiver. Ghost signal in adjoin channel can be eliminated by instant frequency measurement technology, the disadvantage of fixed threshold detecting can be overcome by no-coherence cumulating technology, and channel striding for broadband signal can be solved by re-filtering technology. The validities of these methods are proved by simulation experiments, and the channelized digital receiver can be practical by these technologies.
