ASSESSMENT OF THE EFFICIENCY OF THE AUTOMATIC INTERFERENCE COMPENSATION SUBSYSTEM WITH COMPENSATION CHANNELS INTEGRATED INTO A PASS-TYPE PHASED ARRAY ANTENNA

Abstract

Continuous improvement of the technology for creating unmanned aerial platforms leads to
an increase in their quantitative composition and the tasks they solve. Installing jamming elements
as a payload on unmanned aerial vehicles (UAVs) makes it possible to study the electronic suppression
of multifunctional radar devices (MRLS) by air defense systems due to the excess of the
jamming numbers over the number of oscillations of the jammer compensator. Since modern caliber and millimeter-wave wavy radars are connected to phased array antennas (PAA), most often
of the pass-through type, the task of increasing the anti-interference channel resource in such
conditions is most relevant. One solution to this problem is the constructive unification (integration)
of the main and compensation subarrays in a common phased array array. This solution
requires a small hardware and software modification, which consists in using a system of additional
receivers with a digital output operating on the main FAR network, which is more economical
when using auxiliary small-sized compensation FARs. The article presents the comparative
effectiveness of the subsystem when exposed to interference with subarrays of compensation elements
integrated mainly by phased arrays and an automatic interference compensator with a large
number of small-sized compensation arrays. The study was carried out by modeling using a simulation
software computer model of the electrical subsystem of periodic periodic interference of a
radar with phased array under the influence of a group of UAVs - carriers of the operating parameters
of the interference. The results of demonstrating the possibility of increasing the antiinterference
channel resource when implementing the proposals of the radar, as well as an increase
in the noise immunity indicator by 1.02...1.23 times compared to the radar, equipped with
small-sized phased array compensation channels
