Aiming at the application requirements of natural objects false targets in laser angle deception jamming, based on the analysis of the energy transmission of jamming and the relationship between the weapon threat angle, ground object inclination, incident angle and reflection angle in the jamming process, the energy distribution model of natural object false target established. According to the established model, the simulation study on the disturbance energy distribution of sand and gravel and building features is carried out. The simulation results show that under the same conditions, the sand and gravel features have better interference effect than the building features. The interference energy reflected from the same ground object increases with the increase of the angle of the ground object. For the building false target with better diffuse reflection characteristics, when the ground object inclination is constant, the reflection energy is the largest when the threat angle roughly coexists with the ground object inclination. For sand and gravel targets, there is a mirror reflection component with the change of the inclination angle of the object, which makes the threat angle and the residual angle of the inclination angle of the object deviate, and the deviation angle is approximately a Gaussian distribution. The research results have certain guiding significance for the application of false target of natural objects.
