摘　　要：以RCS分布模型中最典型的χ2模型为例,分析了起伏目标回波统计特性,推导出单脉冲起伏目标、脉冲积累后起伏目标的检测概率计算公式,并画出相应的检测性能曲线。脉冲积累后起伏目标的检测概率公式填补了目标特性领域在该研究方向上的理论空白,可用于研究脉冲积累下任意起伏目标的检测性能,为目标散射特性研究、雷达系统设计及车辆自动驾驶提供了重要的理论支持。Taking χ^2 model as the most typical example of the RCS distribution models, the statistical characteristics of fluctuating targets were analyzed, the computational formulas of detection probability of monopulse fluctuating targets and pulse integrated fluctuating targets were deduced, with the corresponding detection curves drawn. The formula of pulse integrated fluctuating targets filled the theory blank in the field of target scattering, which could be used to study the detection performance of any fluctuating target. The results provided important theoretic supports for target scattering characteristics, radar system designing and. vehicle auto- mated driving.
