摘要
针对雷达信号和杂波信号的频率特点,提出了运用小波包理论中的最佳基加阈值处理的方法进行雷达信号的处理,并用模拟的数据进行仿真实验.仿真结果表明,利用小波包理论进行雷达信号的处理,能够较好地抑制杂波,减弱杂波对信号的干扰,提高了对信号的识别能力.
According to the characteristics of radar and clutter signal, the best bases of wavelet packet and threshold processing are used in radar signal processing. The simulations with analogic data show that the radar clutter can be better suppressed by wavelet packet and the identification of radar signal is improved.
