| 摘 要： | 提出一种光电成像探测系统的性能预测方法。介绍包含传感器、处理器的探测系统模型。根据信号检测理论，以最小错误概率准则设计似然比探测器，利用中心极限定理计算错误率。实验结果表明，随着量化位数的增大，系统错误率逐渐减少，且计算错误率与仿真错误率趋于一致。

| Abstract: | This paper proposes a performance prediction method of photoelectric imaging detection system. It designes the detection system model including the sensor and processor. Likelihood ration test detector is designed under minimum error probability which is based on signal detection theory. Analytical expression of false probability is derived based on central limit theorem. Experimental results show that detection error rate drops with the quantitative digits improving, arid calculation error rates and simulation error rates are basically the same. |
