Radar Cross Section (RCS) Measurement and Evaluation System

Model No. XRC

KEYCOM develops various radars for versatile applications based on its knowledge and expertise on millimeter wave and microwave technologies. KEYCOM’s product line of radars includes Radar Test Systems (RTS) to evaluate distance accuracy or output, Radar Alignment Systems (RAS) to help you adjust the alignment of radars, and Radar Cross Section (RCS) measurement systems to measure RCS of such radar targets as aircraft, ships and automobiles.

1. Radar Cross Section (RCS) Measurement and Evaluation System

Imaging Radar   Approach Type RCS Measurement System
RCS04   RAT08
1. RCS (Radar Cross Section) measurement
- Creates images of reflection signals from targeted objects that actual collision avoidance radars are intended to receive, nearly real-time.
2. Intruder monitoring, moving target monitoring (whole surrounding monitoring option available)
3. Level gauge
4. Fluid flow analysis
  It measures RCS heading toward targets with slow speed.
It moves several times changing the height of radar, and moves toward targets.
To do so, it removes the multipass from the road and the run way.
RCS Imaging Evaluation System   Cylindrical type, Near/Far-Field Conversion RCS Measurement System
RAT06   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.
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.
  RCS03 combines the vertical motion of the 2 probe antennas and the rotary motion of the sample to perform near-field measurement in a spiral shape, then converts the result into far-field.
Compact Range, Near/Far-Field Conversion RCS Measurement System-01   Compact Range, Near/Far-Field Conversion RCS Measurement System-02
RCS01   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.
2. Rotary motion of the target in Az direction enables omniazimuth measurement.
3. 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.
4. 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.
  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.

2. Its log amplifier enables highly accurate receiving level measurement, and converts it to DC voltage.<br />
3. Distance accuracy: ±15cm.<br />
4. Because it is a specified low power device, no radio license or certification necessary.
  1. Spherical type
  No directionality, simple operation.
2. Triangular trihedral type (corner reflector)
  Wide directionality
  Laser pointer installable (option)

3. RCS Simulation Software

RCS Simulation Software (ACES)    
Highly accurate, fast processing PTD method is most ideal for RCS simulation of automobiles, ships, or human bodies.
Because electromagnetic wave dispersion is invisible to the naked eye, the simulation technology has always been the focus in the field. Many techniques such as numerical solutions including the method of moments, physical optics approximation (PO), and the hybrid method that combines the two are being practiced for dispersion evaluation of electromagnetic wave, and among many others, KEYCOM’s PTD-adopted software SFW03, a revision of PO, is highly accurate, fast processing and suitable for large models.
