Weak signal enhancement in radar signal processing

In through wall tracking of multiple targets it is able to detect many times only a target moving closest to the radar antenna system. It results from the fact that the reflections from targets located further from the radar antennas are very week in comparison to that target. The methods for weak signal enhancement can solve the outlined problem. In the paper, three such potential methods are described and tested on real radar signals. The achieved results confirm their ability to enhance the weak signal components with low computational complexity.
