1.RCS (Radar Cross Section) measurement |
The system sends and receives pulsed waves as it moves toward the target whose RCS you want to measure. It measures the RCS , and fits it to the radar equation to obtain correct value. Through making several measurements by changing the position of radar or target, you can see how the multipath on the road surface affects the results. It is also possible to set up a fence in the middle to measure, avoiding multipath effects. |

1.3. RCS Imaging Evaluation System [RAT06] | 1.4. Cylindrical type, Near/Far-Field Conversion RCS Measurement System [RCS03] | ||
The visualization of the distribution of electromagnetic waves reflected
from machines and other objects can contribute to the improvement of
radiowave-absorbing materials and the shape of machines. |
By combining the vertical movement of the two probe antennas with the rotational movement of measuring objects,it performs cylindrical near-field measurements and converts the measurement results into far-field. |

1.5. Compact Range, Near/Far-Field Conversion RCS Measurement System-01 [RCS01] | 1.6. Compact Range, Near/Far-Field Conversion RCS Measurement System-02 [RCS02] | ||
1. 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. |
RCS02 irradiates a rotating sample with plane wave and receives reflected wave at a desired angle. It then executes near-far field conversion on the received data to acquire RCS. |

1.7. 76.5GHz RCS Quasi-Far Measurement System [RCS04] | |||
This is a system which simply measures RCS (Radar Cross Section) at 76.5 GHz. The RCS value is calculated from the dBm value of the target using a corner reflector of an already - known RCS value as a reference point. In conjunction with the rotating stage, the measurement can be performed while rotating the target at any angle range. |
