摘要： Systems and methods for providing wide field-of-view radar arrays. Quadrature phase-shift keying (QPSK) beam forming reduces side lobes by applying a phase shift to transmitted signals to selected transmitting antennas. Super-hemispherical radar coverage at high gain in both broadside and end-fire directions is provided by beam directing elements mounted to a printed circuit board.
