本报告考虑了当目标具有起伏横截面时，脉冲搜索雷达探测目标的概率。推导了四种不同目标起伏模型下的探测概率公式，给出了探测概率与距离的关系曲线。研究表明，对于这些起伏模型，如果距离足够短，起伏目标的检测概率小于无起伏目标的检测概率，而如果距离足够长，起伏目标的检测概率大于无起伏目标的检测概率。波动和非波动情况的差别取决于波动的速度和波动的统计分布。第307页的图18显示了无波动情况和所考虑的四种波动情况之间的比较。
This report considers the probability of detection off a target by a pulsed search radar, when the target has a fluctuating cross section. Formulas for detection probability are derived, and curves off detection probability vs, range are given, for four different target fluctuation models. The investigation shows that, for these fluctuation models, the probability of detection for a fluctuating target is less than that for a non-fluctuating target if the range is sufficiently short, and is greater if the range is sufficiently long. The amount by which the fluctuating and non-fluctuating cases differ depends on the rapidity of fluctuation and on the statistical distribution of the fluctuations. Figure 18, p. 307, shows a comparison between the non-fluctuating case and the four fluctuating cases considered.
