基于高重频超宽带电磁脉冲的ISAR干扰技术研究

With the capacity of all-time, all-weather, and high resolution, Inverse Synthetic Aperture Radar (ISAR) is widely employed in military field. It is of great significance to develop an efficient ISAR jamming technology for improving our survival probability. UWB pulses jamming based on high power, high repetition frequency have properties of good concealment, wide spectrum coverage, less parameters of jammed radar and fast response.. Research on ISAR jamming technology based on high repetition frequency UWB pulses, the project mainly includes three inspects: 1) aimed at the characteristics of ISAR, study adaptive design methods of high repetition frequency UWB pulses waveform; 2) Active jamming technologies based on high repetition frequency UWB pulses; 3) the smart jamming technique of high repetition frequency UWB pulses.. According to above mentioned studies, the jamming mechanism of high repetition frequency UWB pulses to ISAR can be made clearly, the theoretical relation model will be constructed between both offensive and defensive parameters, the technology of high repetition frequency UWB pulses with be optimized for ISAR.
