Abstract
Radar and electronic warfare systems comprising a variety of continuous transverse stub antenna arrays combined with a radar and electronic warfare subsystem. A passive one- or two-dimensional passive electronically scanned antenna radar system is provided when the continuous transverse stub antenna array is fabricated from voltage variable dielectric material. A two-dimensional active array radar system is provided when active array transmit/receive modules are used in conjunction with the voltage variable dielectric continuous transverse stub antenna array. The passive radar system include a continuous transverse stub antenna array, a transmitter, a receiver/exciter, an analog signal converter, a radar display, and a signal processor for processing received radar return signals to produce a radar image. A power supply provides power to the components. A high voltage power supply is provided to drive the voltage variable dielectric material to achieve beam scanning. The electronically scanned and active array radar systems use a voltage variable dielectric continuous transverse stub array. The radar system additionally comprises a plurality of discrete phase shifters coupled to the array. A beam steering computer sets the phase-shifters to steer a radar beam produced by the antenna array in the H-Plane to a desired pointing angle. he high voltage power supply steers the radar beam produced by the antenna array in its E-Plane. The continuous transverse stub array comprises a radiator, a cold plate, a plurality of transmit and receive modules including a feed air strip, a power filter and distribution printed wiring board, and a monopulse network for providing signal outputs that include a sum signal, an elevation signal, an azimuth signal, and a guard signal.
