Compact Range, Near/Far-Field Conversion RCS Measurement System-01
System No. RCS01

Model No. rcs01


·The measurement antenna attached to the mast that is movable in EI direction receives the plane wave transmitted by the compact range antenna in near-field after reflected by the target.
·Rotary motion of the target in Az direction enables omniazimuth measurement.
·Monostatic measurement is made possible when the receiving antenna is placed in the center plane of the compact range antenna, and bistatic measurement when the antenna is placed off the center plane.
·Received data is converted to far-field mathematically to create RCS and images.
·Not only monostatic but bistatic RCS can be measured by integrating Cassegrain antenna.
