Traditionally RCS measurements are carried out in Frequency Domain. Usage of short
impulses as test signals enables to do RCS measurements in wide frequency band. ISAR
Imaging is RCS density plot. ISAR Imaging is used for measurement and modeling the
properties of different scattered targets. High resolution images can be achieved using Time
Domain measurements. Time Domain method allows to obtain substantial advantages:
• Using time windowing it is easy to exclude signal from occasional reflections from
the walls, ceilings and from signal leakage in bistatic and monostatic
measurements.
• Possibility to acquire measurement signals that are asynchronous with interference
from GSM base stations, Radio and TV transmitters and etc. All advantages
enable to carry out measurements without anechoic chamber.
Time Domain Measurement System includes Pulse Generator (30 ps duration),
Sampling Converter (DC-26 GHz), Positionier, Transmitting and Receiving antennas,
Personal Computer. Using pulse drift correction algorithms space resolution is achieved up to
1.5 mm. These results can be applied to non-destructive control, security, and biomedical
imaging.
