Comparative analysis of object shadows obtained by GPS and sound signals

The paper explores the shadows created by moving humans in two types of Forward Scatter (FS) systems, which use GPS signals and sound signals. The comparative analysis of results is based on the correlation analysis and focused on establishing of relationships between different types of shadows. The results show whether it is possible to use sound barriers for detection of moving objects.

TARGET DETECTION USING FORWARD SCATTERING RADAR WITH GPS RECEIVERS

A possible algorithm for target detection in a GPS-based Forward Scattering Radar is considered. The FSR system consists of a transmitter mounted on a satellite of GPS and a receiver located on the Earth’s surface. Theoretical calculations are presented using the secondary application of the GPS L5 signal. The numerical results illustrate the idea of target detection in GPS-based FSR.

Feasibility of asteroid detection using pulsar FSR-network

The feasibility of asteroid detection using the Forward Scatter Radar Network that exploits three pulsars as transmitters is examined. We provide a power budget estimate for asteroid detection using such a FSR-network with the radio telescope used as a receiver. The numerical results are obtained for two known radio telescopes in the Netherland and three known pulsars.
