基于分数阶Fourier变换的阵列雷达运动目标检测算法
A array radar target detection algorithm based on fractional fourier transform
摘要
Abstract
Sidelobe cancellation technology is a spatial filtering technology which widely used in array radar. It can perfectly restrain interference under ideal interference. However, in the context of non-ideal interference, interference suppression performance of its sharp decline. At this point, if matched filter detector in use, due to lack of SIR will affect the signal detection and parameter estimation. In this paper, the authors proposal to use fractional fourier transform detection methods after the use of spatial filtering which can increase the SIR, and through theoretical and simulation prove the effectiveness of the method.关键词
