摘要
Abstract
The adaptive filter, which can effectively increase the ability of the radar to adapt to the complicated electromagnetic environment, is widely used in radar signal processing. Its core technology is to design the filter on the basis of the response of the target to the illumination signal as well as the change of the electromagnetic environment so that it can adjust its structure parameter and finally present itself in a stable state. In this paper, the basic principles of the adaptive filter and the LMS algorithm are introduced. Then the defects of the LMS algorithm are presented. On the basis of this a jamming waveform is designed and analyzed. Finally, the jamming effect of the wave on the LMS algorithm is simulated with Matlab. The jamming waveform prevents the adaptive filter from auto- mation and therefore degrade the performance of the radar.关键词
