Abstract:
The article presents the analysis of the requirements to the digital beamforming system of the conformal antenna array radar providing simultaneous review over a full upper hemisphere. To simplify the digital beamforming system it is proposed to choose the steps of the azimuth beam steering according to the location of the elements on the circumference of the antenna array. On the basis of the investigated requirements and features of the conformal antenna array digital beamforming system, it is suggested the low-cost and relatively simple design of the digital beamforming system.
