穿墙目标探测的Burg算法

Brug Algorithm of Through-wall Detection

详细介绍了电磁波照射人体的散射特性的基本原理,分析了在雷达回波中提取人体运动的信号特征参数的方法。针对穿墙雷达系统中回波信号结构复杂、信噪比低,提出了利用Burg算法进行人体运动特征探测的可能性,并与经典的FFT算法进行了分析比较。通过试验结果分析比较,得出了Burg算法探测能力要优于FFT算法,验证了新算法的有效性。

In this paper, the basic principle of scattering characteristic of electromagnetic wave irradiating human body is introduced, and the technique of extracting characteristic parameters of moving body signals in radar echo is analyzed. Aiming at the problems such as complex structure and low SNR of radar echo, a possibility of extracting the parameters of moving body using Burg algorithm is proposed, and then this algorithm is compared with FFY. At last, it is educed that Burg is better than FFT through experiment, and the effectiveness of the new algorithm is verified.
