摘　　要：研究机载预警雷达在地海杂波背景下探测效能的变化,为提高预警机探测效能提供依据。从信号处理的角度评估机载预警雷达的探测效能,分析探测效能的指标;建立机载预警雷达探测模型、地海杂波辐射模型,利用Matalab软件仿真了预警雷达在不同地形(海情)对散射系数的影响,深入研究机载脉冲多普勒雷达在地海杂波环境中探测低空目标的过程,得出探测概率与信噪比的关系;利用VC++软件进行仿真,结果表明,提高了机载预警雷达在地海杂波中的探测效能。This paper mainly studies airborne early warning radar to detect changes in performance under ground and sea clutter, to improve early warning detection performance. This paper analyzes the detection performance of airborne early warning radar using signal processing method. First we establish the early warning radar models and simulate radar detection procession by Matalab software. We analyze the impact of different clutter on the detection performance. At last, we simulate the performance of early warning radar in ground and sea clutter using VC＋＋.
