Summary

Introduction

UWB radar represents a modern, sophisticated and powerful device designed for non-destructive measurement methods based on electromagnetic waves [1]. As an example, searching for people trapped by an avalanche [5], or in other situations [6], can be mentioned, where the different view on the given situation is crucial to decide for the optimal solution When it comes to the mobile device, the power consumption has to be considered. To use the UWB nodes in the MIMO configuration [9], it is necessary to synchronously control the transmitting as well as the receiving circuits, which is a challenge for design and realization of accurate timing circuits, e.g. for measurement start. Pros and cons of our experimental results are summarized in the conclusion
