Conical rubber based radar absorbent material (RAM)

Broadband, Conical, Weather proof, suitable for sea applications RADAR Absorbent Material.

Conical Rubber Based Radar Absorbent Material (RAM)

  • At Normal Incidence & Upto 45o from Normal: Min. reflection loss (angle of incidence equals angle of reflection) w.r.t metal plate of same size shall be -15dB at 5.0 GHz, rising to min. -17 dB at 8.0 GHz and min. -20 dB at 10.0 GHz and higher frequencies in both polarizations.
  • At 60o From Normal: The reflection loss is down by less than 5 dB w.r.t normal and upto 45o performance at all frequencies and in both polarizations.
  • Under Wet Condition: Performance under wet condition remains practically unchanged w.r.t dry condition performance at all angles/polarizations /frequencies.

DESCRIPTION

Broadband, Conical, Weather proof, suitable for sea applications RADAR Absorbent Material.
Conical front side to face radiation to be absorbed.
Walk-able: CRA-18, CRA-18-P & CRA-18-P-M is rigid enough to be used on walk on areas.
Frequency region: 5.0 GHz to 18.0 GHz and beyond.

FEATURES

Performance under wet condition remains practically unchanged w.r.t dry condition performance at all angles/polarizations /frequencies.

MATERIAL PROPERTIES

  • Basic Composition: Loaded Rubber.
  • Working Temperature: -50 ºC to + 80 ºC.
  • Thickness: 18 to 20mm.
  • Base Size: 300mm X 300mm.
  • Weight: Approx.1.3 kg of 300mm X 300mm size sheet.
  • Color: Black for CRA-18, CRA-18-P is painted (as desired) version of CRA-18.
  • Type of Paint: Polyurethane type suitable for outdoor (ship born) applications.

AREAS OF APPLICATION

  • For radar signature management by covering the ship mast.
  • To avoid the ground reflections at open area test sits (OATS).
  • To eliminate interferences and unnecessary reflection.
  • To avoid the cross talk between transmitter and receiver antenna.
  • On ship borne mast and other out door applications, etc
