摘要：Modern guided missiles are often equipped with homing heads which operates in the radar band. They are located under the dielectric nose radomes which have a significant impact on the main radiation charakteristiks of the homing head. This leads to a decrease in the level of the main maximum of the radiation pattern (decrease in antenna gain),the blur of zeros of the radiation pattern and the deviation of its maximum. In this regard,the problem of astimation the negative impact of the radome on the main radiation characteristics of the homing heads becomes relevant. It must be taking into account when designing the homing heads and in the development of combat algorithms for guided missile weapons. One of the simplest in production are pyramidal radomes. They can be considered promising for hypersonic missile weapons. The article presents the results of calculating the radiation characteristics of aperture antennas covered with nose dielectric radomes of the described type. To solve this problem,we use a method for calculating the radiation characteristics of homing head antennas placed inside the nose dielectric radomes. This method was developed previously at Kharkiv National Air Force University. It's based on the calculation method for field generated by radiation aperture given that an arbitrary system of scatterers (particularly,radome) exists in its vicinity. The method can be used for other types and shapes of radomes. It can also be used to evaluate the scattering characteristics of homing heads under radomes. The article discusses three types of nose radomes with pyramid form. They differ from each other in the number of edges. On the basis of the obtained calculation results,recommendations on the choice of the optimal radomes wall thicknesses were given. The angle errors made by the radomes for different scanning angles of the homing head antenna are estimated.
