Data acquisition, processing, and visualization in microwave holography with probe tracking and positioning on video

Abstract

This paper focuses on the development of the new holographic subsurface radar data acquisition technique in which the position and the polarization of the microwave probe are established by its tracking with video. This technique allows adaptive interactive data acquisition when probe trajectory could not be predefined or be equally dense in the areas with no target. The data processing technique is based on an FFT-algorithm which allows interactive operation. The concept of the data acquisition is demonstrated on the data obtained with a prototype of the system consisting of a holographic subsurface radar and a web-camera. Contrast markers are used to detect and track the antenna. Further development of the system is suggested. The augmented reality devices are considered as more suitable systems for the realization of the considered technique.
