New spatial overlap method of transmitting beam for airborne phased array radar

A novel scanning structure of cross-circumscribed beam overlap arrangement for airborne planar phased array radar is presented, which can reduce the beam shape loss under the triangular and rectangular beam overlap arrangements. The beam shape loss and energy distribution and the probability of central detection of these structures are analyzed and compared. Simulation results show that the cross-circumscribed lattice has the lowest beam shape loss, and it can elevate the probability of central detection, and in favor of the integrality of scanning.
