RCS Imaging Evaluation System

Model No. RAT06

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.

In addition, it is possible to compute the RCS for each part of the system or for the entire system by performing synthesis considering the phase of the reflected waves.

1.The narrow beam can be received by using the large caliber lens antenna. It can display a clear image.
2.It is possible to arrange it on the axis line of the lens for the transmission with a miniaturized antenna.
  As for it, accuracy high, mono-static RCS (radar cross section) can be calculated.
3.A part of RCS such as airframes such as the air intake manifolds of the engine can be calculated.

This system is designed for use in an anechoic chamber.

If you are going to implament test outdoors and measure an actual machine, it is necessary to reinforce micro-wave output, reduce frequency band, expansion of the quantity of antenna movement.
