Air is not the only medium that can spread and can be used to detect speech. In our previous paper, another valuable medium — millimeter wave (MMW) was introduced to develop a new kind of speech acquisition technique [6]. Because of the special features of the MMW radar, this speech acquisition method may provide some exciting possibilities for a wide range(More)
The physiological parameters monitoring of human target are considered to be a meaningful and challenging task in non-lineof-sight (NLOS) scenes such as rescue of trapped survivors in postdisaster. In this paper, a new method based on developed adaptive line enhancer (DALE) is proposed to monitor vital signs via ultra-wideband (UWB) radar with centre(More)
A new non-air conduct speech detecting method is introduced in this paper by means of millimeter wave (MMW) radar. Due to its special attribute, this method may provide some exciting possibility of wide applications. However, the resulting speech is of less intelligible and poor audibility since the present of the combined and colored additive noise. This(More)
Besides air conduct speech, the non-air conduct speech may provide some exciting possibility of wide applications. This paper explores a new non-air conduct speech detecting method using millimeter wave radar. However, the combined noise which is introduced in the detecting system corrupted the non-air conduct speech greatly. Therefore, this study proposed(More)
