一种新的警戒雷达抗同频干扰技术
A New Technique against Common Frequency Jamming between Warning Radars
摘要
Abstract
Suppression of common frequency jamming between same type warning radars is studied. According to the feature of fixed scan cycle of mechanical scanning warning radar,a new rotating cycle moving target de-tection(MTI) cancellation technique against common frequency jamming is presented. Mathematic model for common frequency jamming of warning radar is established,and the reason why conventional MTI technique can-not eliminate common frequency jamming is given. Because common frequency jamming varies slowly and regu-larly,rotating cycle MTI technique extends the MTI cancellation period to antenna rotation period,so as to a-chieve better jamming cancellation effect. Both theoretical analysis and simulation results prove that this new rotating cycle MTI technique is effective in term of common frequency jamming suppression.关键词
