GEAR IDENTIFYING AIRCRAFT Russian patent published in 1997 - IPC

FIELD: radiolocation, identification of classes of air targets. SUBSTANCE: gear known before and based on comparison of radar portraits of real targets with standards did not provide for high authenticity of identification of aerodynamic flying vehicles in dynamics of their flight in turbulent atmosphere at various aspects. For achievement of higher authenticity of radar identification of aerodynamic flying vehicles in quasi-optical region of reflection of radio waves it is proposed to supplement mix of gear with synchronizer, generator of linear frequency modulated signal, second mixer, power amplifier, modulator, reference generator, first and second delay lines, first, second and third adders, first and second full-wave rectifiers, first and second integrators, weight amplifier, divider and identification unit properly changing internist couplings. Usage of evaluation of angular correlation of fluctuations of effective area of scattering of various aircraft at equally spaced sighting angles achieved by new design of circuit of identifying gear provides for increment of authenticity of correct identification. EFFECT: increased authenticity of radar identification of aerodynamic aircraft. 1 dwg
