FIELD: aviation.

SUBSTANCE: invention relates to radar, in particular to methods of integrating an on-board radar station of a manned aircraft and on-board radar stations of unmanned aerial vehicles (UAVs) in determining the delay time for triggering the payload of unmanned aerial vehicles and can be used for effective use of the payload of unmanned aerial vehicles. According to the present method, on board each of the unmanned aerial vehicles, an array of values of the effective scattering area of an air object σ and an array of values of the horizontal angle of an air object ϕ measured with it are calculated by means of an on-board UAV radar station by analogy with a manned aircraft. The minimum and maximum values of the angles of the horizontal view ϕ_min and ϕ_max are identified. The range of variation of the angle of the horizontal view Δϕ=[ϕ_min, ϕ_max] is determined. The average value of the effective scattering area of the air object in the measured range of angles of the horizontal view Δϕ is determined. The results of calculations are transmitted via radio correction (radio communication) channels on board a manned aircraft, where both the average value of the effective scattering area of an airborne object determined in the onboard radar station of a manned aircraft and the average values of the effective scattering area of an airborne object generated and transmitted by unmanned aerial vehicles enter a multichannel calculator (filter), at the output of which an updated average value (estimate) of the effective scattering area of an air object σ is formed, an updated average value of the effective scattering area of an air object σ is transmitted to the board of unmanned aerial vehicles, the current value of the horizontal angle of an air object ϕ and an updated value of the dimension of the air object ("large", "medium", "small") are used for calculation on board unmanned aerial vehicles of the value of the delay time for triggering their payload.

EFFECT: invention is aimed at increasing accuracy of measuring the effective scattering area of an air object in flight, as well as accuracy of determining the delay time for triggering the payload of unmanned aerial vehicles interacting with this air object.
