In the IR imaging system, results of target detection are uncertain because of the affects of noise. Detection Probability is generally used as a criterion to judge an algorithm for detetion. This paper presents a method of calculating the detection probability under contrast threshold detection. The relationship of detection probability with SNR, contrast and threshold is also given.
