Lots of explanation such as radar, sphere, measurements, measuring system, and range are presented in this paper. The paper tells you explanation about the received signal, the conductive sphere, radar system, technique, and the transmitter power.
Inside this paper you can read information about signal, bistatic radar system, transmitter power, wavelengths, and distance. These are excerpted from the paper:
Double-antennas EHF AM transceiver measuring system (TRX MS) for to measure signals scattered by objects, when the system is situated in its near-field zone, is briefly described. Physical Optic (PO) simulation of the radar system and experimental measuring of signals scattered by the conductive sphere of 30 wavelengths diameter, which were measured in distances to the sphere from ~ 10 up to 2000 wavelengths are presented and discussed. Keywords –transceiver bistatic measuring system, RCS in nearfield zone, avoid collision systems
In addition, this paper contains information around systems, system, transceiver measuring system, conductive sphere, and transmitting antenna.
