摘要
LFM信号是脉冲压缩雷达的常用信号,针对脉冲压缩回波信号中混有噪声,采用小波分析对其进行消噪。对多个目标的回波进行了仿真,结果表明该方法具有较好的抑制高斯杂波的能力,提高了信噪比,即使目标回波淹没在噪声中,去噪之后也能够识别出来,具有较强的目标识别能力。
LFM signal is a common signal in pulse compression radar.Wavelet analysis denoising is used for echo signal of pulse compression radar.The echo on multiple targets is simulated,the results show that the method has a better ability to suppress Gaussian clutter and the signal to noise ratio is improved.Even if the target echo is drowned in the noise,the denoising signal can also be identified.
