摘要
Abstract
In order to improve the inhibiting ability of communication countermeasure system to the interference signal,a method of adaptive side⁃lobe cancellation is proposed in the paper,in which the main receiving antenna is adopted as the log periodic antenna,and the auxiliary antenna as omni⁃directional antenna. Without considering the effects of mutual coupling,the analytic expressions for signal⁃interference⁃ratio of output signals after side⁃lobe cancellation are derived,which can serve as a useful theoretical base for selection of auxiliary antennas gain. The computer simulation the results confirm the inhibiting ability of method to suppress any jamming signal. The method improved the detection capability of communication countermeasure system.关键词
