基于谐波模型的生命探测雷达人体状态识别方法

Abstract

Abstract: The life detection radar is developed for human life signals detection, location and status recognition by the doppler effect of body movements, breathing and heartbeat.In this paper by analyzing experimental data, a colored Gaussian noise model and a harmonic signal model are proposed, with model parameters estimated by the high-order cumulant.Then the method for human status recognition is proposed based on the characteristic of life signals.Experimental results confirm that the method has a high recognition rate of greater than 90%.

Key words: life detection radar, harmonic retrieval, status recognition, model
