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

FIELD: airborne radars. SUBSTANCE: method involves directing the antenna beam to given j-th direction (width of antenna beam is equal to θ (0.5), ranging the detection sector of radar in each j-th direction during time interval t_j,. Number N of possible j-th directions in detection sector (θ total) conforms to equation N q (total) / q (0.5). Detection sector of radar is divided into K sectors which width equals to width sector for receiving signals by average radar. In addition K = θ_total/θ_r, width of detection sector of radar conforms to equation where k is number of sector (k 1, 2, K); j is number of positioning of beam in k-th sector (j 1, 2, l); θ_jk is width of antenna beam for level of half power when beam is directed to j-th direction of k-th sector. EFFECT: increased stability to noise. 1 dwg
