Characteristic analysis of anti-jamming device under ultra-wide bandwidth pulse
With the continuous development of anti-jamming devices, the jamming effect of interference pulses for RF links is more and more limited. Ultra-wideband electromagnetic pulse has become a new type of interference means with its own wide spectrum and steep rising edge characteristics. Based on the high re-frequency ultra-wideband pulse, this paper investigates the effect of high re-frequency ultra-wideband pulse on the anti-jamming performance of adaptive zeroing antenna and PIN limiter. The model is built based on Matlab and ADS simulation software, and the simulation results of ADS are verified by the experimental platform. The experimental results show that: for the adaptive zeroing antenna in the navigation receiver, the UWB interference pulse can cause saturation effect on its RF link, which makes the power-inversion algorithm invalid, and then zero-trapping can not form in the direction of the interference; for the PIN limiter, the UWB interference pulse can cause an obvious spike leakage effect. Compared to narrow-spectrum high-power microwave pulses on the nanosecond scale, UWB pulses are more capable of interfering with limiters.
