摘要
从机载雷达的功能仿真模型出发,讨论了机载雷达功能仿真中目标探测过程。分析了探测过程中典型态势取样的信息。分析了大气衰减系数的计算模块,建立了典型背景条件下地杂波、海杂波、箔条干扰杂波、气象杂波的计算模型,给出了典型有源压制干扰的功能模型。并基于上述模型进行仿真实验,比较分析了各种态势下不同背景因素对机载雷达目标探测性能的影响,仿真和分析结果表明了该模型的合理性和有效性。
Through analyzing the airborne radar＇s functional simulation, the typical situation sampling was analyzed in the target - detection process. On this condition, the attenuation coefficient of electromagnetic wave reduced by atmosphere precipitation was analyzed under some typical situation conditions. The clutters of land, sea and weather were established under some typical background conditions of radar environment, and the active suppressing jamming was analyzed under some typical enactment conditions. Based on the models built in this paper, some simulation tests were carried out. Several signifyicant facts＇ effect on airborne radar＇s effectiveness was analyzed. The test and analysis results prove the models＇ rationality and validity.
