Radar

ARA produces RADAR antenna solutions for a variety of applications to include Marine, Weather, and Military systems.

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 20 years.

MILITARY

Monopulse Tracking Antennas

Monopulse tracking is available in reflector antennas for RADAR, RCS measurement, telemetry, and may also be used for 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.

1. 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.
2. 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).

WEATHER

Understanding weather patterns is an important tool for public safety and agriculture to ensure that the proper steps are being taken before storms. Properly monitoring weather patterns helps with preparation to limit damage and administer the proper size of response needed during and after major weather events.

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 that meet RADAR suppliers most stringent requirements. Antenna feeds for all bands and reflectors measuring from 2 to 28 feet in diameter provide the necessary specifications for the operation of a high-performance weather RADAR system.

Our standard products include single and dual polarization designs that offer high cross-polarity with low side-lobe performance, while providing maximum gain. ARA’s signature Weather RADAR antenna systems are integrated with our positioners and controllers.
