中文摘要：
从复杂背景下机载雷达的目标探测模型出发，分析了探测过程中的各种态势信息，研究了态势取样的过程。在此基础上，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。并基于上述模型进行仿真实验，对比分析了背景杂波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。
英文摘要：
The target-detection of the airborne radar is based on the complex background facts. Through analyzing the target-detection, the situation information in the target-detection was described, the situation sampling process was analyzed. On this condition, the clutters of land, sea, weather and chaff jamming were established in some typical background conditions of radar environment. Based on the models built in this paper, some simulation testing were carried out. Several signifying clutters＇ effect on airborne radar＇s effectiveness was analyzed. Those testing and analysis results prove the models＇ rationality and validity.
