VAN ATTA ARRAY FOR RADAR OBJECTS IMITATION

L.G. Kornienko, O.V. Kolomiytsev
Annotations languages:

Expressions for directional, polarisation, frequency and power characteristics of re-radiated field of Van Atta array were derived and analysed with respect to polarised fields ration and oscillators conformance. Antenna array that provides imitation of radar objects in the conditions uncertain radar location and polarisation was studied.
Keywords: directional antenna, Van Atta array, radar object, oscillator, diagrams of re-radiation, field polarisation, vector of polarisation, Radar Cross-Section, gain factor, antenna aperture, antenna pattern
