MARINE AND PERIMETER
ARA designs and manufactures an array of Marine RADAR and Perimeter Surveillance Antennas covering S-band and X-Band frequency ranges. Our Division in Pembroke, MA, offers either linear or circular polarized products with 27 dBi to 35 dBi of gain. ARA’s signature Marine RADAR antennas have been meeting or surpassing industry standards for over 15 years.
Monopulse Tracking Antennas
Monopulse tracking is available in reflector antennas for RADAR, RCS measurement, telemetry and other applications. It may also be used airborne and shipboard antenna systems.
Flat Arrays and Box Horn Arrays
Our line of patented Box Horn Arrays or BHA Series antennas are ideal for high power RADAR applications when small size is important.
- RDA, BHA and BAA Series “Normal Beam” Flat Antenna Arrays: These arrays provide a “Normal Beam” radiation pattern where the main beam is accurately perpendicular (normal) to the face of the array and to the rear mounting surface.
- TWA and TAA Series “Traveling Wave” Flat Antenna Arrays: These antennas have their main beam located at an angle to the normal position of the array aperture. The resulting radiation is polarized in the plane orthogonal to the beam tilt. TTP Series polarization rotators are available to rotate the polarization to another plane. The beam tilt changes with frequency in these arrays (useful in frequency-scanning radars and other similar applications).
ARA designs and manufactures a complete line of Weather RADAR antenna systems. Antenna systems operating in C-band, X-band, S-band, Ku-band, and Ka-band and meet RADAR suppliers most stringent requirements.
Antenna reflectors measuring from 2 feet in diameter to our newest 28 foot design provide the necessary specifications for the operation of a high performance RADAR system.
Our standard products include singular and dual polarization designs that offer high cross-polarity with low side-lobe performance, while providing maximum gain. For example, a premium design offers side-lobe performance of -30 dB in a 4.2 meter reflector antenna at C-band. We continue to work with our customers to design new and more efficient antennas that allow for added performance in their Weather RADAR systems. ARA’s signature Weather RADAR antenna systems are integrated with our positioners and controllers.
