专利汇可以提供Method and means for jamming radio transmission专利检索,专利查询,专利分析的服务。并且1. A jamming system for interfering with a pulse radar signal including a transmitter tuneable to the radar carrier frequency, a random noise generator, means connected to the output of said random noise generator for selecting random noise of frequencies above the radar pulse repetition frequency, means connected to the output of said last named means for modulating the transmitter in response to the selected random noise, and receiving means operative to reject all the modulation frequencies of said transmitter and pass the radar pulse repetition frequency, whereby the radar transmission signal having a carrier frequency substantially the same as the transmitter frequency may be monitored during operation of the transmitter.,下面是Method and means for jamming radio transmission专利的具体信息内容。

1. A jamming system for interfering with a pulse radar signal including a transmitter tuneable to the radar carrier frequency, a random noise generator, means connected to the output of said random noise generator for selecting random noise of frequencies above the radar pulse repetition frequency, means connected to the output of said last named means for modulating the transmitter in response to the selected random noise, and receiving means operative to reject all the modulation frequencies of said transmitter and pass the radar pulse repetition frequency, whereby the radar transmission signal having a carrier frequency substantially the same as the transmitter frequency may be monitored during operation of the transmitter.
2. The method of jamming a periodic signal comprising generating an interference signal of proximate frequency, generating a random noise signal, selecting random noise signals of frequencies above the periodic frequency, modulating said interference signal with said selected random noise signals, transmitting said modulated signal, and maintaining said signal on the frequency of the signal to be jammed by receiving said signals, rejecting all the modulation frequency components thereof above said predetermined frequency to isolate the low frequency components of the communication signal, reproducing said low frequency components, ascertaining the carrier frequency thereof, and adjusting the interference signal carrier frequency in accordance therewith.
