DEVICE FOR ADAPTIVE MANAGEMENT OF SPECTRAL DISSIPATION CHARACTERISTICS OF A RADIOLOCATION OBJECT Russian patent published in 2008 - IPC G01S7/38 

FIELD: radio engineering, possible use for reducing radiolocation noticeability of an object.

SUBSTANCE: device includes control block, knowledge base, onboard radio reconnaissance station and multi-channel generator of control signals, N controllable nonlinear radiolocation deflectors, connected in a certain manner. In adaptation mode, device ensures minimum of intensities of spectral components of dissipated field at irradiation frequencies by causing influences in controllable nonlinear radiolocation deflectors, which are formed by multi-channel generator of control signals, parameters of which are determined by control block on basis of information contained in knowledge base, which is accumulated during training mode. As control signal for controllable nonlinear radiolocation deflectors, a signal may be used which represents an additive mixture of constant shift voltage and monochromatic oscillation with frequency, which exceeds supposed pass band of radiolocation station receiver of the opponent, or a signal, which causes appearance of new spectral components in receiver band, disruption of response modulation rule of matched filter in radiolocation station of the opponent and results in substantial reduction of signal to noise ratio at its output.

EFFECT: improved quality of radio-counteraction to radiolocation stations of the opponent by means of semi-active adaptive management of spectral dissipation characteristics of the object being protected.
