The relevance of the work is due to the need to create wearable complexes of high-precision weapons based on guided 10 mm caliber and subcaliber projectiles aimed at the target (ground defenses, armored vehicles, helicopters) using a stationary radar station in the centimeter or millimeter wave range.

The results of the conducted patent search indicate the high relevance of tasks aimed at improving the efficiency of the homing of guided missiles. At the same time, an increase in efficiency is achieved both by improving the hardware (antenna systems) and by improving the algorithms for the functioning and the search for new methods. The paper investigates antenna elements based on Vivaldi antennas, located on the rocket stabilizer consoles, as well as microstrip-type antenna systems. The advantages of these types of antenna elements are good integration into the geometry of a rocket or projectile, as well as the ability to receive a signal from both a stationary radar station and a reflected signal from a target. It is noted in the work that antenna systems of this type do not create additional resistance to the oncoming air flow in the process of moving the rocket or projectile to the target, thereby not having a negative effect on the speed characteristics of the rocket.

The research methods are the numerical analysis of the characteristics of antenna systems using the Weiland finite integration method, implemented in the space-time domain, as well as field studies of the antenna system layout, consisting of Vivaldi antenna elements.

As a result of numerical simulation, the radiation patterns of the individual elements of the system have been obtained, as well as the total radiation patterns in the case of quadrature powering of the antenna elements. Directional patterns have been presented both in space and in the form of projections in the azimuth and elevation planes. The paper notes that presence of a rear lobe in the directional pattern of the antenna systems under study allows for a stable connection of a rocket or a projectile with a stationary radar system.

The results of field experiments are the amplitude-phase characteristics of the signals taken from the outputs of the elements of the antenna system model. These characteristics have been measured at different angular positions of the rocket relative to the target, as well as in two different conditions of the layout and target location: indoors and outdoors at a distance of 16 m. Based on the results of mathematical and field experiments, conclusions have been drawn about the prospects of using the considered antenna systems as transmitting and receiving antenna systems for homing heads of guided missiles and sub-caliber projectiles with a caliber of 10 mm.
