Abstract:
This paper focuses on scientific issues related to new application of GPS in radar networks that use the effect of Forward Scattering (FS) of electromagnetic waves to detect and estimate targets on their GPS radio shadows. The aim of the paper is to describe the experimental study of GPS radio shadows of different objects irradiated by GPS signals and to develop a possible algorithm for signal processing of the radio shadows of objects. Registration of FS-GPS radio shadows from moving targets is performed using a small commercial GPS antenna and the stationary receiver. Topology of the experiment meets the requirements for the appearance of the FS effect. The results presented in this article show that from FS-GPS radio shadows of different objects can be extracted information about the parameters of the object including size, speed and direction of movement, distance to the receiver. The information extracted from FS-GPS radio shadows of objects can be used in different applications including radio barriers, security, classification and identification of moving and stationary objects.
