Dynamic FLAPS (TM) Electronics Scan Antenna for Space System Radar

An electronic-scan radar antenna, especially if useable in both microwave and millimeter-wave bands for surveillance, tracking and imaging functions (active and passive) would be a major asset for future space and missile systems. Now, twenty-five years since their introduction, multi-band, affordable cost phased-array antennas (especially with potential commercial application) are still not within sight. Malibu Research believes we have a potential way around this impasse based on a dynamic version of our proven FLAPS phased-surface antenna technique. Our FLAPS phased-surface has the capability of directing RF in specific design directions through the use of arrays of varying length shorted dipoles to generate any surface phased gradient. To date, we have manufactured FLAPS antenna surfaces using printed-circuit techniques to obtain fixed beams. However, a means exists to vary the beam electronically by dynamic variation of the dipole pattern. Specifically, we propose to accomplish this by using a programmable plasma display--similar in nature to plasma display television and laptop computers. The key points, as delineated in our proposal are as follows: a) The proposed technique is a merger of two advanced but proven technologies; i.e., FLAPS and plasma display. b) The plasma display elements are highly RF conductive ionized gases. c) The resolution, speed and huge number of computer updatable display elements yield a highly dynamic, large RF size electronic antenna with multi-band capability.
