METHOD OF TARGET DESIGN AUTOMATION AT AIMING AT HELICOPTER COMPLEX

摘要

FIELD: military equipment.;SUBSTANCE: method relates to military equipment, in part of onboard armament sighting systems of helicopters using different methods of aiming guided missile guidance systems. According to the method of aiming at the helicopter complex, when using the optical-electronic system of an OPS, the operator is able to observe the scene and to detect targets at long ranges and with better resolution, rather than if it would be monitored using an optoelectronic system mounted on the missile, having the worst angular resolution. Image with an OPS is recalculated taking into account the metric (image_1, further – standard) to the image taken from the sensor of the rocket chamber (image_2), the image_1 is only a fragment of the image_2, with preservation (albeit coarse) of all features of the scene area in form of certain brightness anomalies of both the target and its immediate environment. Then, metric alignment of these two images is performed, considering the fact that both images are obtained at one time and from one place (albeit from different sensors), then it can be stated that these images are very similar. Differences are observed in the brightness pattern and the noise level. Subsequent processing by the gradient regional operator contrasts the brightness anomalies of both images, which enables to find the position of said fragment (reference) on image_2 and specify a target designation point using correlation comparison means with the normalized cross-correlation function.;EFFECT: technical result of the method is to reduce the time for capturing the target by the operator and to increase the operating range of the missile, which is ultimately equivalent to reducing the probability of hitting the helicopter with means of object air defense.;1 cl, 1 dwg
