DNA Project 609 Island Radar Phased Array.
Abstract
The report describes the design and development of an electronic-scan phased-array antenna system and a digital clutter-mapping system for use with the DNA Project 609 400-MHz radar system. The phased array is capable of plus or minus 20 degrees of electronic beam steering and full hemispheric mechanical steerability. It is composed of 780 short-backfire radiators with a total gain of 36 dB. It is vertically polarized and has phase-monopulse-tracking ability. The electronic beam forming and steering is controlled by a digital system using a PDP-11/20 general-purpose computer system. The same computer is used to control the digital clutter-mapping system which is composed of an A/D converter, multiplexer, digital tape recorder, high-speed disk storage, and an intensity-modulated graphic recorder. The digital mapping system is capable of sampling the phased-array radar video data and presenting a variety of three-dimensional plots of radar clutter data. (Author)
