摘要
以信干比增益作为衡量标准来定量研究超宽带(UWB)无线电引信抗噪声和正弦干扰性能。详细推导了存在高斯白噪声和正弦干扰时相关接收的信干比(SIR)增益;得到了影响UWB无线电引信抗干扰能力的信号特征参数;指出了提高其抗干扰性能的措施;并进行了仿真计算。仿真结果与理论分析吻合的很好。定量分析与仿真结果表明:超宽带无线电引信具有较强的抗干扰性能;增加调制周期和信号带宽可提高引信抗噪声干扰能力;采用脉冲重复频率捷变技术可提高引信抗正弦干扰能力。
The anti-jamming performance of ultra wideband（UWB） radio fuze was quantitatively researched based on the criterion of signal to jamming ratio（SIR） gain.The SIR gain was deduced in detail under the noise and sinusoidal jamming;the signal characteristic parameters affecting the anti-jamming performance of UWB radio fuze were obtained;the measures to improve it were proposed,and emulated calculations were carried out.The simulated results are in good agreement with the theoretical analyses.The analyzed quantitatily and simulated results indicate that UWB radio fuze has strong performance of anti-jamming;its anti-noise jamming performance can be improved by increasing modulation period and signal bandwidth;its anti-sinusoidal jamming performance can be improved by pulse repetition frequency agility.
