间接可编程陷波法在警用扰频技术中的应用

Method of Indirect Programmable Trapping Wave Applied to the Technology of Disturbance Frequency Used by Policemen

详细地分析了一种新型的可编程陷波技术。该技术采用二次线性频谱搬移,仅在较低频段使用一个高Q值的带阻滤波器,即可在较大频带范围内对信号实施间接的可编程陷波。在警用扰频技术领域,间接可编程陷波法有着极其独特的应用优势,使用他可以在干扰频段范围内任意开辟出一个通讯频段窗口。对该方法如何在警用扰频技术中应用做了详细的分析和说明。

It analyses a technology named indirect programmable trapping wave. In this method, the technology of linear frequency spectrum convert has been used two times. At the same time it only uses a high Q Band Rejection Filter（BRF） in relatively lower frequency,this indirect programmable trapping wave in wide range of higher frequency will be accomplished. In the fields of the technology of disturbance frequency used by police,there is perfect usage with this indirect programmable trapping wave. It could open a communication band in jam - band willfully. This paper gives minutely analysis and explanation about how to use this technology in police - disturbance - frequency.
