摘　　要：为了限制雷达辐射,提高雷达的隐蔽性,研究了给定雷达辐射时间和能量限制下的雷达最优脉冲积累检测问题,提出了一种最优脉冲积累数的选择模型,分别得出了确知脉冲串相参积累、随机相位脉冲串积累、随机振幅相位脉冲串积累情况下单脉冲信噪比与最优脉冲积累数的对应关系。研究结果对给定辐射时间和能量限制下提高雷达目标检测数目及跟踪精度有一定的理论和实际意义。To constrain the radar＇s radiation and increase radar＇s concealment capacity, the radar optimum pulses accumulation amount for target detecting with emission time and energy constraints is studied. A choosing model for radar optimum pulses accumulation is established. Corresponding relations of single pulse signal noise rate and the optimum pulse accumulation amount respectively for certain signal pulse string accumulation, random phase signal pulse string accumulation and random phase and amplitude signal pulse string accumulation are deduced . These conclusions can be used for reference, in the theoretical and practical way, in increasing amount of targets detected by radar and improving tracking precision.
