摘要
深入分析了侦察台对跳频通信发射机侦察中的截获概率与搜索带宽之间的相关关系,提出了接收端采用宽带搜索以提高扫描速度的侦察方法。运用数据融合方法很好地解决了因搜索带宽增加而导致的测向精度下降问题,克服了宽带搜索方法的缺陷,从搜索速度和检出概率2个方面提高了接收机端的获情效率。通过案例分析,验证了数据融合算法的有效性,从而证明了整个侦察测向方法的可行性和优越性。
This article thoroughly analyzed the correlation between capture probability and searching bandwidth of frequency hopping communication system. And a ce method based on wideband search was suggested to promote searching rate. Data fusion was used to solve the problem that direction finding accuracy would get worse if searching bandwidth was expanded. In this way the disadvantage of the method was overcome, and the system efficiency was improved. Case study has demonstrated the advantage of this fusion algorithm, And the feasibility and superiority of the method was also proved.
