Abstract

Abstract

The application of conformal sparse array to airship-borne passive radar is studied, and the target detection performance of airship-borne passive radar is analyzed. Because of the importance of antenna in radar system, embattle method of sparse array Digital Beam Forming (DBF) antenna and antenna pattern index are selectively analyzed. Layout of airship-borne sparse array is implemented based on the combination of Barker code. In order to obtain ideal DBF antenna pattern, a method of compensating the curve array to the linear array is proposed. With respect to the possible deformation problem, the distributed Position and Orientation System (POS) is used to measure the deformation error based on which curve fitting is implemented to conduct accurate compensation. Simulation results show the effectiveness of the proposed method.
