With much of the literature on four-arm spiral direction-finding technology scattered among the government and private companies, no single document on the subtleties and intricacies required for a high performance system has been available to the general antenna community. Four-Arm Spiral Antennas rectifies this omission. Two of the outstanding experts on spiral antennas offer you the first original treatise on four-arm spiral antenna design and applications. A practical design guide using easy-to-understand principles, this text gives antenna engineering professionals and practicing antenna design engineers what they need to design direction-finders for satellite tracking systems and missile antennas for homing on radio frequency transmitters.
