Research status and prospects of UWB radar life information recognition for mine rescue

Gong-kuang zidonghua
Ultra-wide band (UWB) radar can penetrate non-magnetic media such as coal and rock to detect life information of personnel after collapse. Due to the complex mining environment, UWB radar loaded with vital sign signals is prone to interference from ...

Multi-channel noise radar

, 2006
A noise radar system consisting of an array of K transmit antennas and M receive antennas is considered. Two implementations are considered: in the first, a single noise source is, after appropriate phase shifting, transmitted; in the second approach K ...
