In this paper,the jamming effects of sunlight reflections from strong reflective sources are analyzed and measured empirically using a precision turntable,a specular reflection device and open field images equipment.Measurement show:sunlight reflection interference effects pixels can be up to 20 times of ideal imaging pixels；stronger interference effect and flicker,the air to ground imaging equipment stable tracking caused by the larger impact.The full process of external sunlight reflection interference experiment is difficult to realize.In this paper,an experimental method based on the measured sunlight interference effect,simulating the scene image containing background,target and interference injected into the air ground imaging equipment to obtain tracking guidance data,and bringing the data into the ballistic calculation model.The final jamming effects of sunlight reflection on the air to ground imaging equipment are analyzed.When 10km interference is effective,the landing error is greater than 450 m；5km interference is effective,the landing error is greater than 25 m,the protected target needs to take certain measures；if the interference distance is not less than 10km,even if the person in the loop to relock the target,the fall point error is greater than 110 m.This paper has certain significance for the improvement of anti sunlight interference algorithm and the evaluation of anti interference ability of air to ground imaging equipment.
