Abstract
Ultra wideband (UWB) radar allows us to track people in critical environments and situations. However, the results of application of single UWB radar have shown the reduced ability to detect the other persons if some person is located between the radar antennas and the rest of persons. The described negative phenomenon is consequence of the mutual shadowing between people. In the paper, we will outline three potential solutions of this effect. They are based on application of UWB radar network, weak signal enhancement and high-up setting of radar antennas. The experimental results achieved with these approaches confirm the suppression of the mutual shadowing effect.
