【摘要】 利用雷达式非接触检测系统可检测到生命参数信号(呼吸、心动等信号)。本文运用BP神经网络的误差反向传播算法进行了仿真实验,并对非接触生命参数系统采集的随机噪声背景下的生命参数信号与纯噪声信号进行了有无生命信号的模式识别、分类实验,实验结果表明该算法简易、实用。更多还原

【Abstract】 Life-parameter signals such as respiration and heartbeat could be obtained through radar non-contact detecting system, the theory of BP neural networks was used to process some signal which was received from the modeled signal and the non-contact life-parameter detection system, so that we can investigate the result of signal processing based on BP neural networks. We analyze the result of these tests, and point out the problem in signal processing based on BP neural network at last更多还原
