Johnson criterion-based laser interference effect simulation evaluation method

The invention relates to a Johnson criterion-based laser interference effect simulation evaluation method. Comprising the steps that a system model of a non-cooperative photoelectric imaging system is established, and the system model at least comprises the imaging resolution, the distance of a detection target and the size of the detection target; calculating the number of pixels before laser interference according to the imaging resolution, the distance of the detection target and the size of the detection target; calculating a laser interference influence coefficient; calculating the number of pixels after laser interference according to the number of pixels before laser interference and the laser interference influence coefficient; according to the number of the pixels before laser interference and the number of the pixels after laser interference, the laser interference effect is calculated, and the Johnson criterion is used for conducting simulation evaluation on the laser interference ...
