Antenna For Shipboard Missile Detection System

Millimeter-Wave Antennas with Integral Downconverters

About the Technology

A great deal of interest and effort has been directed toward the development of Millimeter-Wave (MMW) missile seekers, over the years. Relatively small antennas can provide high gain and narrow beam width at MMW frequencies. The MMW technology can penetrate fog, smoke, clouds, and dust, and because of its short wavelength, can provide sensing accuracy, when used in sensor systems such as radars. It is widely projected that anti-ship missile systems will operate in the Ka-band and W-band where low atmospheric attenuation windows exist around 35 GHz and 94 GHz, respectively. In order to defend naval ships against such missiles armed with MMW seeker technology, detection systems with a high probability of detection and intercept are needed.

QuinStar Technology, Inc. has developed high gain MMW omni directional antennas, direction fi nding antennas, and integral up converters, for the 30-40 GHz and 90-100 GHz bands, where missile attack threats are deemed the highest. The key elements of the MMW receiver systems are the down converters and antennas, which can detect vertical and horizontal polarizations. 

Military and Commercial Significance

MMW antennas can be used to upgrade existing systems, or as the front-end of new naval electronic warfare systems and implemented across several classes of ships. The MMW antenna provides enabling technology for the development of new systems and other applications including high data rate communications, force protection, surveillance, homeland security, and Unmanned Aerial Vehicles (UAV) control and data transmission.
