摘要
针对机载雷达二维空间小区引导搜索的应用,建立了小区引导搜索的成功引导概率模型。为便于与定点搜索、自主搜索方式进行射频隐身性能对比,给出了引导搜索的射频隐身性能指标计算方法。仿真结果表明,小区搜索相比于定点搜索能大幅度提高成功引导概率,相比于自主搜索能显著降低搜索时间、减小被截获概率。
For the application of regional cued search in two-dimensional space by airborne radars, a model describing the successful guiding probability of regional cued search is presented. For ease of comparing with the fixed-point cued search and the autonomous search in term of the radio frequency stealth performance, the method of calculating the performance index of radio frequency stealth of cued search is proposed. Simulation results show that, compared to the fixed-point cued search, the regional cued search can improve the successful guiding probability greatly. Compared to the autonomous search, it can decrease the search time and the intercepted probability significantly.
