摘　　要：针对现有评估指标不能全面反映相控阵雷达在搜索状态下的抗干扰能力的问题,提出了利用搜索效率抗干扰改善因子这一综合指标来衡量相控阵雷达搜索状态下的抗干扰能力的方法。建立了在有源噪声干扰下搜索概率计算模型以及采用脉冲累积和累积检测技术后搜索概率的计算模型,通过分析脉冲累积数N和累积检测数M的关系,给出求解最大搜索效率的方法,最后通过实例仿真和结果分析,表明该方法计算简单,科学高效。Some indexes can merely evaluate part of the antijamming ability of phased array radar working in search state. In order to settle the problem, a new method of detecting efficiency EIF is put forward by referring to integrated index. It can evaluate roundly the antijamming ability of phased array radar working in search state. Firstly, the calculation model of detection probability interrupted by active noise jamming and the calculation model of detection probability with impulse aecumulation and accumulation detecting technology are built. By analyzing the relationship between N and M, a method is put forward to calculate the max of detection efficiency. Finally, example simulation and result analysis have verified the simple and scientific features of this method.
