Inherent ECCM Evaluation and Simulation of Typical CW Modulation Proximity Fuze

研究典型连续波调制无线电近炸引信抗干扰性能的测度问题。在简要分析有源干扰机理和模糊函数理论的基础上,提出用一定高度的模糊函数截面面积作为无线电引信固有抗干扰性能的测度指标。利用该方法仿真分析并比较了伪码调相和线性调频引信在相同的等效带宽下的抗干扰性能。该测度理论给出了连续波调制引信抗干扰性能的统一测度方法,客观、合理的,且具有可计算性,可应用于工程实践。

A study of ECCM Evaluation of Typical CW Modulation Radio Fuze was made. Based on the analysis of active jamming mechanism and ambiguity function, an evaluation methodology of radio fuze inherent anti-active-jamming performance was proposed using the area of the ambiguity function cut at a certain height. And it was applied evaluating the anti-active-jamming performance of pseudorandom binary-phase-coded modulation continuous wave fuze and linear frequency modulation fuze with the same bandwidth. A generalized ECCM evaluation methodology Typical CW Modulation Radio Fuze was given. The simulation shows that the evaluation methodology is impersonal, reasonable and computable, which can be use for practical purposes.
