Disruption in the DSMAC Positioning System in Cruise Missiles

In this paper, the cruise missile’s DSMAC positioning system is simulated based on correlation. Then, in order to create a disturbance and analyze the effects of each disturbance in the performance of this positioning system, items such as changing image resolution, brightness, ambient coverage, viewing angle and other random variables such as artificial changes (smoke) were used. In order to determine the area of defense operation against this system, considering the missile inertial navigation system error and the possibility of circular error (CEP), it has been proved that the DSMAC location is within a radius of three to five kilometers from the target. By analyzing the obtained results, it has been shown that the areas with more black pixels, such as forest areas, are undesirable areas for DSMAC. In addition, by using jamming in the cruise missile altimeter system, the accuracy of the missile altimeter process can be reduced so that the image positioning system is completely disrupted. Also, the larger the size and area of the total artificial changes (smoke) and the color of the changes, in proportion to the background of the image, the disruption and defense against the DSMAC system will be possible. Finally, by providing operational scenarios, the defense against the cruise missile DSMAC positioning system has been realized.
