Bistatic noise radar demonstrator with phase-interferometry for bearing determination

Abstract

In the paper bistatic noise radar is considered. The concept of such a radar is verified with a demonstrator. The demonstrator consists of physically separated transmitter and receiver, therefore a bistatic geometry is created. Reference signal used for correlation processing is generated locally in the receiver. Coarse synchronization in time and frequency between the transmitter and receiver is provided by GPS (Global Positioning System) satellite navigation. Fine time synchronization is carried out using the direct path interference signal. Apart from range and velocity measurements, bearing is also estimated using phase-interferometry technique. The demonstrator has been tested and verified during a field measurement campaign. In the paper the results of synchronization, detection, localization and tracking of a moving target are presented.
