- Raw thermal images acquired by pulsed thermography ( pt ) usually have low signal noise ratio ( snr ) and temperature contrast
摘要脉冲热像检测中直接获取的原始热像往往信噪比较低、对比度较差。 - Experiment results show that in low bit rate environment , the new image compression scheme performs better than jpeg in the aspects of perception and psnr ( peak signal noise ratio )
实验结果表明该算法在低码率下，相比jpeg ，获得了在视觉效果和峰值信噪比方面更好的恢复图像质量。 - Finally , by using mismatched filter technique , optimized code is studied and searched . this kind of code will be used broadly in the future because it has the property of no sidelobe and low snr ( signal noise ratio ) loss
最后，采用失配滤波器技术，研究并计算机搜索了距离旁瓣为零而信噪比损失很小的优化码，该优化码可有良好的应用前景。 - In order to improve signal noise ratio ( snr ) , wavelet denoising is used , and the radar in - pulse characteristics is extracted by wavelet - ridge , radar emitter signal sorting is realized by neural networks
该方法首先对接收到的雷达信号进行小波去噪，达到提高信噪比的目的，然后利用小波脊线法准确提取其脉内特征参数，最后基于神经网络实现信号的分选。 - The maximum likelihood estimator ( mle ) approach is an important one in frequency estimation domain . this approach has the merit such as exhibiting best performance and requiring minimum threshold of signal noise ratio in calculation
最大似然频率估计法是该领域中的一种重要的研究方法；该方法具有估计结果准确，计算所要求的信噪比门限值低等特点。
