Abstract
Not Available Among different methods using electomagnetic impact to disable radio-electronic devices the most effective one is the use of a series of video pulses of duration ¿ 10 ns. A series of such pulses with repetition rates of several hundred hertz lowers the sensitivity of protection circuits by up to two orders of magnitude. We propose to use microwaves as a carrier frequency with video modulation. Microwave radiation can be formed as a narrow wave beam that sufficiently increases the power flow on the target, consequently increasing the processes of rectification in the irradiated radioelectronic elements. This combination of using a narrow directed wave beam with pulses of duration of about 10 ns will generate an effective tool for far distance disabling of electronic circuits. A mobile device using a high-power L-band vircator already exists and operates in the single pulse regime. However, the vircator cannot operate as a HPM generator of high rate repetition pulses because of the position of electrodes in the interaction space. The proposed development of HPM X-band sources which are capable of operating at a high repetition rate, with bursts of short pulses and in automodulation regimes, will permit us to build a far distance HPM disabling device consisting of a system of focusing the wave beam and a high current electron gun able to operated at high repetition rate pulses. In addition to functioning as an electromagnetic impact device such a set-up can also be used for distance testing of radioelectronic devices and as a nanosecond radar with high interference immunity and high resolution.
