Abstract:In this paper, the problem and difficulty of changing antenna radiat ion patterns is presented. According to the study on directional characteristics of the lo op antenna, a cross antennas weighted method is proposed which can chang e rapidly and exactly the direction of antenna radiation patterns after weig hting signal by the weighting coefficients when the antenna can not be rotated . Finally, application of the cross-antennas weighted method is discussed and p rospected.The method has features of higher reliability, higher precision, eas y to automatic control and independent on platform direction. Using this method has great significance to improve direction finding(DF) positioning accuracy, reconnaissance intercep ted probability and communication reliability.
Keywords:direction finding  loop antenna  cross antennas weighted method  antenna radiation patterns
