ADAPTIVE POWER-CORRELATION SYSTEM FOR SUPPRESSION OF SIDE LOBES OF ANTENNA DIRECTIONAL PATTERN Russian patent published in 1998 - IPC

FIELD: antenna equipment. SUBSTANCE: outputs of main and N additional antennas are connected to main and compensation interfaces of self-balancing potentiometer which output is connected to gate. Output of adder which adds output signals of additional antennas is connected to controlled amplifier. Gain of controlled amplifier is set by signal from output of unit which calculates suppression rate of self- balancing potentiometer using signals from analog-to-digital converters which are connected to outputs of adder and self- balancing potentiometer respectively. Signals from output of self- balancing potentiometer and controlled amplifier are detected and compared with respect to their power in calculating unit. Resulted difference is compared to threshold. If it is exceeded, system fires gate which serves as system output. EFFECT: increased probability of detection low-level jam setters in presence of heavier jam setters operating along side lobes of directional pattern of main antenna of direction-finder. 4 dwg
