| 摘 要： | 将WVD和Hough变换相结合,利用时频聚集性和Hough变换点的累积得到的信号的检测结果,用来检测雷达目标回波信号。然而在强干扰低信噪比下检测能力有限。利用线性调频信号瞬时频率的线性特征,只采用信号WVD时间段的中间部分值进行Hough变换,在时频平面上对WVD的结果进行时间轴上的截取技术,对检测算法作了改进。通过仿真结果表明,改进的检测算法在低信噪比和强干扰环境下能有效地检测出目标信号。

| Abstract: | WVD and Hough transform are combined to detect the radar target echo signal,by making use of time and frequency domain accumulative performance of WVD and cumulative points of Hough transform.But the performance is limited in strong interference and low signal and noise ratio(SNR) background.An improved method is presented for it,by using of instantaneous frequency feature of linear frequency-modulated signal,only make Hough transform for the middle part of WVD time domain.Time axis interception method is t... |
