Design of an X-band Phased Antenna Array on Parabolic Reflector Antennas with Beam Steering by Phase Center Displacement Control

The instrumental capabilities for existing antenna systems are extremely limited and the development of fundamentally new measurement methods and options for their practical implementation is necessary. The relevance of the choice radio telescope designs in favour of a phased array antenna also lies in the possibility for using a scanning beam, which allows searching and obtaining information for the primary processing of data on finding small space objects such as space refuse. Using the example of development and the results presented in this paper, it is proposed to study the possibility for constructing such phased antenna arrays from highly-directional airborne elements at space stations, the projects of which have not yet been implemented. For this purpose, algorithms for analyzing the phase information of scattering objects in real time should be considered. The paper presents the results which are obtained by the authors by designing antenna array, the high gain and sidelobe reduction of 3 dB in comparison with a traditional linear antenna array.
