摘要
基于MUSIC算法可以很好的区分多个目标信号的特点,用它对生命探测雷达接收的人体呼吸回波信号进行理论推导,并用MATLAB进行仿真,根据峰值频率的情况可以看出胸腔幅度是否发生变化,来证明生命体有无呼吸,即可证明有无生命体存在。
MUSIC-based algorithms can distinguish between a good number of target signal characteristics, this paper, it has life-detection radar echo signals received by the human respiratory theoretical derivation and use MATLAB simulation, according to the frequency of peak amplitude can be seen that the chest has occurred change, to prove whether life forms breathing, you can prove whether life forms exist.
