介绍了典型雷达目标的RCS起伏模型，阐述了由雷达目标起伏造成的信噪比损失，分析了雷达发现概率、虚警概率和信噪比之间的关系，绘制了仿真曲线。对非起伏目标和起伏目标之间在相同检测概率下的所需信噪比的不同，给出了一种等效算法，并针对非起伏目标的检测概率复杂度大的问题，给出了一种简化模型，并对简化后的误差进行了分析，最后对模型在雷达检飞试验中的应用进行了简要分析。

A Simplified Algorithm of Target Detection Probability and Its Application

Typical target radar cross-section （RCS） fluctuation models and signal-to-noise （S/N） ratio loss due to target fluctuation are described; relationship between detection probability, false alarm rate and S/N ratio are analyzed, and simulation curve is provided. Equivalent algorithm is presented on the basis that at same target detection probability, different S/N ratios are required for non-fluctuate target and fluctuate target; and a simplified model is designed to solve high complexity of target detection probability against non-fluctuate target, error introduced after simplification is analyzed. Finally application of the model in flight test of radar is analyzed.
