METHOD FOR BEAM CONTROL OF PHASED ANTENNA GRILL Russian patent published in 1995 - IPC

FIELD: antenna devices. SUBSTANCE: method involves sequential movement of beam with fixed sample θ_i in given detection sector, emission of pulse burst to each i-th direction (i 1, 2, N), measuring level of noise signal P_n in each i-th direction. If level of noise signal P_n is greater than threshold value P_thr, then in each i-th direction the beam of phased antenna grill is directed to (i-1)-th direction. Later on, the beam is being sequentially directed to (i-j)-th direction with minimal possible sample θ_j until noise level P_n is less than threshold level P_thr. Number of pulses in pulse burst which is emitted to each (i-j)-th direction is greater or equal to three. EFFECT: increased stability to noise when jamming is affected along side direction of beam pattern. 3 dwg
