目标起伏特性对雷达的检测性能具有重要的影响 ,通常采用的起伏特性模型对小型战斗机起伏特性的近似效果不佳。为了得到更好的近似效果 ,本文在分析杂波中目标相关模型的基础上 ,用某型雷达的外场实测数据对小型战斗机目标的起伏特性进行了深入的分析 ,得到了该类目标起伏特性的修正模型。实测数据的处理结果表明 ,应用修正模型可以显著提高雷达对小型战斗机目标的检测性能 ,取得了良好的效果

Radar target fluctuant characteristics has important impact on target detection performance of radar system. The commonly-used fluctuant model can not achieve desired performance for light fight target. To obtain better approximation, the target correlation model embedded in clutter is analyzed and the modified target fluctuant model is proposed based on the radar real data analysis. The analysis results of real data show that the radar can obtain better detection performance by applying the modified fluctuant model.
